About Me

  1. My glofish have slowly become more silver and the emeralds are developing a light spot between body and tail. My question is, is this natural with age? I've had the larger barbs for around 2 years and the smaller barbs since Feb of this year. There's also 2 bull heads(local stream) and 2 Chinese algae eaters(1 too many). I've tried api phdown with zero success, hoping that's the issue. I found a rock with lime and removed it yesterday. It was in the tank for about a year. There's been no die off or behavior changes. Water temp is 78-84. My thermostat is digital and is terribleness.
  2. I've decided to try 2 different aquaponics approaches for my 2 different 29g aquariums. #1 requires very little in the way of supplies and tools. I just need to gather the right plants. Plants that can grow terrestrially with their roots always in water. I don't keep uncovered tanks, so a fully aquascaped tank with plants coming out of the water surface (as much as I like the look) isn't something I want to contend with. I live in Southern Arizona, where the air is very dry most of the year, and evaporation from an open tank can be outright ridiculous. LOL But, I decided there had to be a way I could get the benefits of the terrestrial plants (more nitrate usage) without an open tank. Was watching a YouTube video (fully open tank, of course), and suddenly inspiration struck. Not rocket science after all! Last night after I went to bed (yes, I SHOULD have been sleeping), I figured out how to pull it off effectively and safely (for the fish AND plants), and cheaply, too. In fact, I already have everything (except the plants) on hand to do it because I'll be using supplies out of my crafting stash. As soon as I start doing that, I'll be sure to post photos to this thread. #2 is a true aquaponics setup. Plumbing, equipment, planter box, and all. I had to do a boatload of research to understand the hows, whys, and whatfors of setting it up, which way I wanted to go about it, and what plants that means I can do. My final supplies for it arrived today. Unfortunately, I'm not feeling well, so I'm not up to doing anything with it. grumble, grumble, grumble Griping aside, I'll be sure to post photos to this thread as I go. Whether successful or not, it should be fun to do anyway. I've never done anything that needed plumbing before, though I've often studied things like sumps in the past (in case I ever do get that big oscar tank I want). I'd love to hear from anyone who has done aquaponics or is thinking about doing it, what kind you're considering, that sort of thing. 🙂
  3. Hello, My LFS gave me this lil guy as an accidental catch when I got some silver tipped tetras. Anyone know what kind this one is that has the black spot near the rear?
  4. Here's some context. Around 3 weeks ago I added a platy in one of my (kinda) new planted tank. And when I say kinda, I mean the tank has been running since last July but I had yet to add any fish in there. Family emergency had me on leave for 3 days. I did a water change a day or 2 before, and I figured if he really got hungry he could've eaten any of the algae I have. I come back, and the platy is pretty motionless with red gills. So I test the water, and everything is good, and the nitrates are around 30ppm, which was about my normal ppm (I had some plants that could benefit off it) and do a water change anyways. So maybe my test was broken, so I took it to the LFS and got it tested, which they said it was fine and offered to exchange it. So I did. After the first couple days I started immediately seeing the same symptoms and water changed every other day. He seemed a little better but still had the red gills. Everything was 0 except nitrates, which were around 10 ppm. Couple days ago I added a small group of pygmy cories. They seem fine as I type this but they also had the red gills the next morning, much like the 2 platys before. Nitrates are still 10 ppm....and there's an HOB and sponge filter getting air in there. And as far as I know, red gills are a sign of parasite, lack of O2, or ammonia burn. But the only thing left are parasites, and I oddon't think they can develop them in less than a day, seeing as they looked fine in the store and the bag. What should I do?
  5. Christmas has not been a happy time in one of my tanks, and I'm at a loss. I had to say goodbye to my much loved Betta this morning, and my dog brought me a kuhli loach on Christmas Eve. Two more loaches are missing and presumed lost. So my 5gal Endor tank is down to 1 endler, 1 kuhli (unless someone is hiding in the At-At deco), 1 nerite snail, lots of bladder snails, scuds and live plants. I had just done regular maintenance Thursday, which includes a vac of 1gal water, replaced with some stress coat and a squirt of easy green for the plants, rinsing the filter floss in the tank water removed, AC strip test. Ph: 7.6 on the low range kit, 7.4 on the high range kit (anyone else have this issue with water right on the transition space between the two tests?) Nitrites and ammonia both 0ppm Nitrates close to 0ppm (floating plants may be up taking most as they are reproducing like mad in all my tanks). Chlorine 0ppm (we have good quality well water, no chlorine added to the water filtration in weeks). Gh/Kh: 60-80, 300 Some background info on the tank if you're still reading: Late August: Tank established with aqua soil, stem plants, terrestrial moss on "trees" and ground, java fern. Mid September: Betta and nerite snail added. Late October: 5 juvie kuhli loaches added. One never really thrived, but did ok. The other 4 always together, always out and got nice and fat from snails and sinking food. Mid November: finished QT of a group of Male Endlers, added 3 to this setup. One died the next day from stress/ph shock (he started in the other betta tank at 6.6ph and was rejected by that betta, do he got drip acclimated between 7.6 to 6.6, then back to 7.6 in one afternoon). All seemed well for 5 weeks, then one of the two endlers disappeared. No body, nothing. This portrait tank has a very good fitted lid, so it was a mystery. I started counting loaches, only came up with 4. The small one was gone. In the last two weeks the betta was increasingly subdued, which with good water parameters I wrote off as him becoming more mature (he was 4months old when I got him). The loaches were always all over the tank and he seemed a bit taken aback by their antics and preferred hanging in the floating plants. But then relaxed became lethargic. I couldn't see any issues or signs of disease at all. Everyone else seemed great. Christmas Eve: I see the dog playing with something on the carpet... one of the loaches. Still fully colored up and wet, so I tried putting him back, but no luck. Lid was on fully, no idea how he made it out. Today: awoke to find Donald dead at the bottom. No signs of distress. Signs of fin rot? So I did another water change this morning including a filter rinse. Can only find 1 loach now, but he seems fine. The endler very active, but probably distressed to be all alone. Wondering if he needs to move to one of the the other tanks. Really frustrating and sad - Donald was my favorite fish we had in three setups. The other tanks are thriving! The only difference in this tank of note is we do two light periods 8am-noon, 6-10pm. I welcome any insights. I've kept fish a long time and it's disheartening to see your animals thrive, then suddenly everything seems to go sideways. Here's my other two tanks - just got baby shrimp in the smaller setup a couple of days ago.
  6. Hello everyone! I'm new! And I have a problem. I have a 7 gallon planted tank with 2 amanos, a few neos, a nerite, some pest snails I can't get rid of, and a Betta. I've had this tank for over a year, and my last fish, Punkin, had been doing great in it until she started doing what I can only call coughing. You can see it in this video. I tried to treat with ich-x, since I've heard that ich can attach to the gills and cause irritation, but she did not react well to it. She almost seemed to have a seizure in response to it, even though Im pretty sure I've dosed her with it before. Regardless, I dosed two times, she had the same terrifying reaction, and quit. After that, I simply tried to treat her with daily water changes. But she didn't get better. It turned into dropsy, which I tried to treat in a hospital tank first with a trifecta of kanaplex, metroplex, and focus, then with maracyn and maracyn2. She didn't get better, and I ended up euthanizing her a few weeks after all this started (SIP Punkin - I miss you sweet girl). Which brings me to now. I reorganized the tank but didn't treat it, convinced at the time that maybe Punkin had died of something genetic. I ordered a new fish after about two weeks, and placed him in there (at this point the tank had been without fish or a heater, though the shrimp and stuff were still in there, for about two weeks, and with a heater but no fish for about a week). It didn't take long for him to start showing the same coughing symptom. I consulted reddit and fishlore, concluded it might be gill flukes (though I'm very open to being wrong, i just want to figure out what's going on at this point), and tried to treat with prazipro. I've treated twice now (1.7 mLs each time, 7 days apart), and thought I was in the clear. Until I saw him cough again today. So clearly I'm not. Which also led me to realize that much of what he's been doing lately in the tank is getting stuck swimming around the pieces of wood i have in the tank, which could be because he's itchy, and not endearingly stupid like I had thought. His pectoral fins have also been kind of ragged, which I had assumed was because of transit at first, but its been at least a few weeks and hasn't gotten any better, so I'm starting to think that might be an issue as well. I unfortunately haven't been able to get a good video of him coughing, but it looks almost identical to the Punkin video. That being said, I've included a few videos that show his fins and the scratching behavior pretty well, so long as you don't mind having a staring contest with a fish lol. I really just want to figure out what to do. I don't want to lose another fish so soon. I have a bucket I could use as a hospital tank around, and I have plenty of meds. I'm even willing to tear down the tank and start fresh, especially since Winter break is around the corner - I would have time then. BTW will post values before the end of the night - still have some last minute studying to do, then I can test the water. Also if need be, I can link the fishlore and reddit threads I've started on this issue too, if they will provide more information.
  7. Hello all, just checked my tank and I saw about 6-7 dead cherry shrimp. I’ve had this colony for about 2-3 years now. I added 10 more within the past month to add a little extra to the gene pool plus 10 Amano shrimp to eat some of the black beard algae in my tank. No idea what caused this die off. Everything else in the tank seems fine including the rest of the colony. pH-7 Nitrates-10 Hardness-300 Nitrite-0 Ammonia-0 KH/Buffer-80 Water Temperature-80F
  8. Above is a clump of gravel that I removed from my tank last week after noticing a white spot on the susbtrate. It didn't have any noticeable smell, even after I broke it apart to see if there was anything inside. I broke it apart completely but made sure to put all the gravel back in one spot to see if it would recombine like a sponge allegedly would. It appears to have done so. Does anyone know what this might be if not a sponge?
  9. I am not sure what this is or where it came from. I don't believe its any kind of eggs of fish in it as they are huge and hard. When squeezed they pop out milky like substance. I have another post with mystery plants that were in the tank, plus I have hygrophila augustifolia and a ludwigia of some sort in the two tanks I have found these. Fish - Fresh Water Bee Gobies, ottos, pea puffers, a couple guppies and lots of red cherry shrimp. Yes my peas do great here.
  10. Hi All: I have problems with my tank, cant figure it out. LFS doesn't know, planted tank forum no help.. Maybe you can help. Might be a bit long to describe.... Tank is 14 months old. Cycled fast. Dirted, planted tank. 32 gal but a bit shallower so say 27 gal. Generally looks beautiful. Fluval plant 3.0 light. fluval 207, heavily planted, aerator, generally stays 77F, slight bit of fluctuation. Have had a bunch of different fish, mostly Scarlet badis, and returned some fish due to incompatibility issues (I returned halfbeaks, bumblebee gobies, peacock gudgeons). Now have a few silver kuli loaches (3), one Annandale loach, 4 ember tetra (just lost one to the weird sudden bloat), about 8-9 exclamation point rasboras, and now down to only 4 scarlet badis. Had up to 13-14 badis, breeding successfully many times over, now Ive lost almost all, all my females gone, my big male has a poor pale color rather than the super bright red they normally had. A few months ago bought 11 (wild caught didn't know at the time) green rasboras (Sundadanio). They were amazingly healthy, got fat, then precipitously died in a matter of weeks. Possibly for them it was the hard water.. They had a bit of ich but that cleared up fast. The badis are my biggest concern. Bumblebee gobies were tail nipping so I got them out. Still, randomly they decline. Some get bloated, many others start by getting raised whitish patches, but not as bright as ich, typically they lose much color, then die. Usually still aggressively feed up till they get bad. My last big female badis was too bloated for several weeks or more.. tried to get her to eat frozen daphnia but she wasn't too into it, then she vanished and a shrimp was eating her the next day. One occasional symptom is the fish will flick as if rubbing their sides.. not common but has happened. My last female badis was doing this a bit at the end .. I feed live black worms that I keep in a separate tank, in RO water and feed them boiled organic broccoli, squash, which they devour. Some sediment in that worm tank gets in during feeding.. I also feed live or fresh dead baby brine almost daily, frozen adult brine and frozen daphnia. Hikari micro pellets for those that take it (tetras and rasboras and loaches only). LFS people say my fish are "spoiled"... Suddenly in the last month or two Ive lost a ton of badis. Always had a slow trickle but many breeding so they were replaced... Ill attach a current badis with a spot on face, and water test result. Water always has zero N so dont ask, no I dont have Chlorine or ammonia or Nitrate or anything. I also have Neocardinia shrimp doing well and Amano shrimp, many snails.. all good. My thoughts: -I put a rock or rocks in there that is leaching something I cant test for.. Tested most with vinegar first, so not sure that it. -I have a piece of wood that is leaching something.. Mostly manzanita but some is mystery driftwood (mostly small pcs) that I previously boiled for hours. I do have a fair bit of tannin build up either from soil or wood. -Ive introduced a disease, bacteria, or parasite by feeding live mosquito larvae or live daphnia I get from local ponds.. Dont really do this often at all but used to a bit more often (still rare, haven't in a while so its odd the die off has increased). -My organic potting soil is too deep and is gassing something; I do *still* get bubbles if I prod the soil with tweezers. LFS recommended I put carbon in the fluval, so I did, chemi-pure elite. That seems to take some of the tannin out but its only been a couple weeks in there. current little male with a spot. Last female shortly before dying, Aug 23. Bloated. Death of a male shortly before that... got bloated fast. General tank look typical water test Thank you for any wisdom and for reading
  11. Hey everyone, I have a question about a disease that I’ve been trying to figure out for awhile now without success. The disease appears out of nowhere, kills quickly and always creates a lot of flaky debris. The first time I saw it was while I was an employee at Petco and it killed an entire shipment of 100 guppies in 24 hours. It just showed up in my 10 gallon planted tank yesterday and it killed my school of Ember tetras in 12 hours, my Pygmy Cory catfish in 24hours, and now my Albino Cory cat and Oto both have signs of it. On my Embers and Pygmy Cory it created a lot of flake, but now it’s starting to behave like ich. I thought it was a bacterial disease the first time I saw it, but then yesterday seeing it’s characteristics I decided it was probably a fungal disease, so I started treatment with API Fungus Cure. Now today I’m thinking it’s parasitic, but I’ve never seen a parasitic disease cause flaking like this. I did a 25% water change to reset the fungal cure I was using yesterday and I started treatment with the Paracleanse, Maracyn, and Ich-X trio today that they sell here on the site. I unfortunately don’t have any pictures of it since everything happened so fast, but I can tell you I recently moved to a new state and this was the first time I used the tap water. The water here is weird and I wasn’t going to use it, but then I did and this happened. The only off thing before this issue appeared was my pH sitting at 6.0 (possibly lower because 6 is the lowest my test kit goes). This tank has been giving me issues as of late, but hasn’t been detrimental until now. Mostly just an abundance of algae growing. The pic is after I started the most recent treatment. Thanks for any help given!
  12. What is this? From a face book post, permission was granted to reach out for answers: As posted; It's growing off a nirate snail. Nothing kills it. And it's hard! It is a snail. Size of a quarter. We have treated the tank with parasite and fungal stuff as well as algae. He moves around well, eats and has grown. We have cut them off but they grow back.
  13. Hello all! I need some assistance figuring out what has developed near my betta gill plates. Any and all advice would be appreciated so I can follow through researching any possibilities. Behaviorally, there is nothing out of the norm for my dragon plakat betta, and as such the ID I've gotten elsewhere as gill hyperplasia does not seem to fit the bill. Water parameters are dialed in and maintained well in the planted community. For reference, I now test with the coop strips. Tank is stable and has been running for six ish months, pH is ~8, Nitrates are <10ppm, GH is ~150, KH is ~120, and water temp is 80 degrees Fahrenheit. Thank you!
  14. I found this on ebay https://www.ebay.com/itm/184942242967 It says its for brine, but I can't see how that would actually work well, or at all. Is this something else that's being sold as a brine hatchery?
  15. Using my aquarium coop test strips was reading high level of nitrites. So i did a 50% water change. I dosed the tank with water conditioner while it was half empty and add water from the tap at the tank’s temperature. I had a platy die, all 14 babies platies alive and the mom hanging out on the surface of the tank. The rams seems like everything is fine and I notice a lot of dead bladder snails. What did I do wrong here? I’m so sad because i felt like I was finally coming to my own (dialed in) and all the plants were looking great and healthy.
  16. Hi everyone I came across this forum on my search to figure out what the tinted/foggy white bubbles on my Betta's lair (his name is Vlad he's a Petsmart 'rescue' it only seemed fitting to give him an evil lair) I've never seen these before so hopefully they aren't harmful he's been through enough already it took weeks to get his color to come through and the fin rot to go away so I'm beyond grateful to have found all of you I'm somewhat new to Betta care I typically have goldfish but after my last two passed away after 8.5 years I wasn't ready for another fish until I found this little guy suffering in a foggy cup Temp= 77° F Nitrates =0 ppm PH= 7.0 ppm KH= 80 ppm GH= 60ppm *KH and GH could be more towards the 120ppm range
  17. So I have a 20 gallon I’ve had set up for about 5 months now. It’s planted with some driftwood and sand. I have 2 mystery snails, a nerite snail and a trapdoor snail (plus babies now - oops). Anyways, anytime I add fish they die within a few days and it seems to happen so fast I can’t catch what’s going on. I first put a school or runny nose tetras in there that were mailed to me - half died in transport so I had went to get some more at my LFS so they wouldn’t be stressed by having inadequate numbers. A couple days go by and they seem to adjusting fine and eating well - then I see one that looks like he has a messed up eye - like it’s squinty. So I’m confused - I go to Facebook and get a ton of diff suggestions. I didn’t have any meds on hand (I now have the coop trio of meds) - so went to a big box store and got some ich stuff but by the time I could treat them after work half of them were dead. I then added the meds and the other half died in the next 12 hours - so within 24 hours they were all dead. It was my first fish dead and devastating. So I waited a couple months and my snails seemed fine. I obviously did big water changes and stuff but everyone assured me that nothing would survive the tank. so I then decided to get one dwarf gourami - seemed fine for the first day and then next morning he seemed to be struggling to breathe but I could see no visual signs of anything. I took even more of my floaters off the top and I have 2 sponge filters with air stones running - so I don’t think it was lack of oxygen. finally I just went to get a trio of guppies as my last attempt and sure enough they are dying. I can’t see any visual signs but they seem to be breathing heavy. I have no idea how to treat my tank in an attempt to save them?! Or even so I can keep fish in this tank. I have 2 other tanks with no issues so this one is killing me. I’m also newer to the hobby my tank parameters are: ammonia 0 nitrite 0 nitrates 20-40 ppm depending on day pH 8 im really hoping I don’t have to tear the whole tank down and start all over again - help please
  18. Hi there! Newcomer to the hobby, here (about 4 months). This tank has 2 pea puffers and some shrimp for some color. My other tank has berried shrimp so I know what that looks like, but no idea what this is. I wouldn’t have imagined my puffers would be breeding so I’m just confused. Thanks so much for any help you may have to offer and hope y’all are staying healthy! edit: I also have 2 Asian stone catfish.
  19. Does anyone know what this may be? I want to ID it before I simply grab the net and remove it from my tank. Thanks!
  20. I have just finished cycling my tank but these white things started showing up on the glass of my planted betta tank. They started small but now they are getting long stringy tails and attaching to my plants as well. They have longer trails by my sponge filter because the flow is stringer. It's a 10 gallon betta tank with a betta and snail. Sorry I really don't know how to post pictures on here so I linked them below. Please help! Thank you! Started like this: https://photos.app.goo.gl/ZErNfutfqC5XPDrS8 Today's pics: https://photos.app.goo.gl/jJM5GHrDMBebo5Bq8 https://photos.app.goo.gl/mc8zLFgxZBUDwcth8 https://photos.app.goo.gl/ZbWQZ74e96PcpKij7
  21. I set up this 90 gallon tank about 3-4 months ago. I took GCory's lead and progressed slowly. Established an undergravel filter, added cryptocene plants (dozen or so), a couple of amazon swords, etc. NO fish yet! Added some biological filtration via a "seasoned" sponge filter. I let the tank "mature" for a couple of months, finally adding some white skirt tetras (5) and did nothing for another couple of weeks. More white skirts. More patience. Two weeks later I added two 3" discus and let them enjoy their new environment. Meanwhile, I was monitoring water parameters, etc...All good. I couple of small water changes (10-15 gallons) All is well. Couple of weeks later, two more Discus. Slow and steady. I even measured out the flake food (1/4 teaspoon) so I would not be overfeeding them. Two weeks later, Cory catfish, about 6 or so, followed by 6 more two weeks later. All is well. Waited two weeks before I added my Blue Diamond (5") Discus and kept a close eye on everything. Water was clear, fish were thriving and besides a couple of 25% water changes it looks a though my "display tank" was becoming a reality. Now in the fourth month, tragedy struck this week. The discus were huddled at the top of the aquarium, but not grasping for air. Just huddled together. Next day, a dead white skirt, then another that evening... I did a 35-40% water change with some fish "improvement" but the white skirt deaths continued, then the catfish, one by one. Another water change (35-40%). Some General Cure meds. Now, a dead discus (3" ones) then another, White skirts all gone. No more catfish. Three more 3" discus. Just the 5" and a couple of 3" discus are left. I expect a total collapse by the weekend. WHAT HAPPENED????? I am at a loss. Blue Diamonds look as though their skin is falling off, except there is no ammonia indicated nor a pH crash. All test "normal". I have had these Discus for over two years, raising them from a quarter size only to kill them in my 90 gallon "dream tank" As a footnote, considering with this tragedy, I had a outbreak of black hair algae. Any thoughts will greatly appreciated.
  22. I found a bunch of these in my shrimp tank yesterday. There is some up high on top of the wood and then mostly down low on my rock cave and substrate. Also see some in the sponge filter There are 5 Red Riley Shrimp and 2 large mystery snails in 15 tall. ph 7.4 ammona 0 nitrite 0 nitrate 10ppm KH 4 GH 9
  23. I have had 5 corydoras in Quarantine for a month now. They have been treated with 2 rounds of paracleanse. They have been growing well and no longer have swollen stomachs. Went to go get them to move to my main tank and found one looking like the picture below taking its final breaths. obviously transfer is on hold. Remaining 4 look fine swimming around. There are bladder snails, MTS, and mystery snails in the tank with Java fern and hornwort. Nitrate is 20-30 temp 78 kH ~3 ammonia and nitrite 0 gH 7 pH 7.8 What could cause this? What do I need treat with again to clear the remainder in quarantine? thanks
  24. First post here and it’s gonna be a long one because I want to give as much info as possible. I've been having a strange issue with my pristella tetras in my planted community tank. I first got them in mid December of 2020 and I want to say it was early February when I first noticed some small dark patches on one of them; It didn’t look like any diseases I’m familiar with and it was only one fish, so I just assumed it was some natural variation in color or scars I hadn't noticed before, but after a week or so the patches were bigger and it started swimming strangely so I moved it to my 10 gallon quarantine tank where it died the next day. It wasn’t until April 14th that I noticed another pristella tetra with similar patches, this time with a growth on it’s mouth and a small chunk of its tail missing. I immediately scooped the fish out and stuck it in a little 1 gallon quarantine tank. The main tank had already been treated with ICH-X as a precaution after I moved in a new neon (for just a few minutes) that had been in quarantine without noticing it’s ich, so that medication doesn’t seem to have an effect on whatever this is. I did start treating the pristella with KanaPlex in it’s quarantine tank, but that had no effect either. I never did see it eat after removing it, and it eventually started to swim very weakly/float around and died on April 28th. The same day that the second fish died, I managed to catch and quarantine a third pristella tetra that I noticed has the same dark patches (noticed maybe 5 days prior, but it was exceptionally hard to catch compared to the others), so far this one is alive but not eating and occasionally swims kinda weakly. I haven’t treated with anything since the meds I have on hand don’t seem to do anything, and I can’t for the life of me figure out what the issue is. The black patches start out just looking like pigmentation, but after a while they seem to turn into raised bumps. My many google searches show nothing that looks the same except for occasional forum posts much like this one where people are confused about dark patches on their fish and nobody is able to give a concrete diagnosis; seems like it’s only tetras but that could just be a product of my search terms. It just seems really strange to me that it’s happening to so few fish, only the pristella tetras so far, and so long after getting them. The aquarium is a heavily planted low tech 55 gallon kept at 75F, weekly water changes of 50-70%, weekly doses of Easy Green and SeaChem Flourish Potassium. Ammonia and nitrites always test at or near enough to 0 ppm that I can’t tell the difference, nitrates hover between 10-20 ppm depending on how long since the last water change, PH is 7.5. Tank stock is 4 pristella tetras (originally 7), 6 neon tetras (more in the quarantine tank until I figure this out), 7 siamese algae eaters, 3 clown plecos, 1 otocinclus, a few dozen endler/guppy hybrids, and a bunch of cherry shrimp; everything else seems perfectly healthy including the remaining pristellas. I feed New Life Spectrum flake food, Hikari micro pellets, Fluval Bug Bites pleco formula, Hikari algae wafers, and Ocean Nutrition instant baby brine, no live foods ever. No fish have been added to the main tank since December other than the one neon for a few minutes and all issues that it and it's quarantine tankmates had have since cleared up. I have added new plants multiple times since first getting the fish so maybe something hitched a ride. Other examples of people with similar looking disease problems, the third link has multiple people reporting similar symptoms: http://www.wetwebmedia.com/PristellaF.htm http://www.wetwebmedia.com/FWSubWebIndex/BlackNeonTetF.htm https://www.aquariacentral.com/forums/threads/anyone-able-to-identify-black-spots.133788/ I don't have pictures of the first fish, so I can't compare to the other 2 and I guess it is possible that what it had was something completely different, which might explain the gap in time between them, but if memory serves me correctly it looked pretty much the same (with the base of the tail being the most prominent dark area) and in the third link above people mention months between infections. It might be worth noting that I had a skinny female guppy die the other day, but I would just assume that was from old age, I can't keep track of all their ages, but there's been a population in there for years so that happens every once in a while and it wouldn't be unusual for them to waste away a bit before finally dying (it had no other symptoms and all other fish seem fine). Any help steering me in the right direction would be appreciated.
