About Me

  1. So I truly love the color and flashy appeal of a school of tetras compared to their price of $2-$4 each. However I truly hate the fact that they’re so skittish and delicate. They hide the moment I’m near the tank and By delicate I mean they die like rabbits from fright. My harlequins however are always front and center. They have a beautiful color pattern and just over all may not be as pretty as the cardinals but offer more as a schooling fish. Is there another nano fish like them with the eye catching colors of a cardinal? Another issue I’m having now is Im losing 1 cardinal a day now. Waters at .25 ammonia 0 nitrites, and 5 nitrates. I think they truly might be starving their selves because they hide when I go to feed them and the harlequins and the betta eat everything. I tried giving a little and letting the others feed then feed them but nothings working. Tried frozen brine shrimp and blood worms, betta pellets, plecco wafers, and flakes. This is a gravely planted tank with hiding places and no sign of aggression from the other fish.
  2. Alright, so I ordered some green fire tetras about two months ago, they went through quarantine, but I noticed this one weird fish that was a little bigger than the rest of them and I just figured it was an older green fire tetra. Two months later and it was not 🤣 It's a diamond tetra so I bought 5 more of them. My question is since the first diamond tetra is by itself with the 9 green fire tetras in my 29 gallon, should I move it back to my quarantine tank to be with the school that I just bought or leave it in the 29 gallon since it's already been through quarantine and there's another school of tetras for it to be around? I don't know if the stress of not being with a school is worse than the risk of it getting sick in the quarantine tank with the rest of the school.
  3. Which one should I get, if some of them can even fit in a 20 g tall planted tank? Want to keep them with honey gouramis (idk 1, 2 , or 3) and a school of pygmy cories. Never kept any tetras or any schooling fish btw, so kind of a beginner. And maybe its because theyre babies but all of them are on the same level of desire for me.
  4. I've done some research and it seems a lot of people say Congo tetra are the largest. I've seen some pretty big Congo tetra, but it seems like Buenos Aires tetra get bigger. Are there any tetra out there bigger than the Congo or Buenos Aries? Also are pink tail chalceus considered tetra?
  5. I have glolight tetra fry that is 6 weeks old. I am going on vacation and don’t have anyone to feed them. There are maybe 20 in a 10 gallon. Been feeding brine shrimp daily. I know all my other fish will be fine for the week but I’m worried about the fry tank i have plants and magnolia leaves in the tank and I plan on doing a water change before I leave and adding a bunch of infusoria/small little white critters that are in one of my other tanks. Will they be okay for the week?
  6. My tetras are a bit nippy towards each other and towards my rather docile betta fish. I've heard that rasboras are quieter and less aggressive. Is this true?
  7. Hi all. Just a test to see how to post. I keep tetras in a heavily planted 40 gallon breeder.
  8. Obviously, many Central and South American Cichlids are enormous. I love watching Canadian mater aquarist Jim Cumming showcase his gigantic cichlids, or watch tanks in the Wessel Fish House. But there are a number of medium-sized Cichlids that would make a meal of a Neon Tetra at first light but won’t bother larger Tetras. So what’s your go-to larger-sized tetras for keeping with Cichlids? Right now, mine are Colombian Tetras. I love the silver-blue with bright red fins. Plus, they school tightly in a large enough group.
  9. I just grabbed these two little guys from my local fish shop. I didn't think they looked the healthiest at the shop but didn't have a chance to get a good look at them until I got home. Both of then look pretty sickly and lack colour. One of them has a large red blotch on one side of his abdomen and the other looks like it has a line of black specks on the top of its head. I've treated the water with Seachem Prime. Should I use anti-fungal or antibacterial for the meds? Sorry about the pics. Hard to get good ones in the quarantine tank.
  10. My Flame Gourami has developed a taste for his tank mates my neon tetras. Is there anything I can do to stop this? Or will I be forced to have a ten gallon tank with only my gourami. I almost think he is just bored.
  11. Need some direction after not finding information on glowlight tetra breeding. so far.... I have a 10 gallon set up for breeding. 6 small magnolia leaves added a week ago (collected from my tree, zero pesticides or anything out here in the country) half tank filled with guppy grass. Small sponge filter. put a dim light on the tank this morning to simulate a sunrise and they did the barrel roll several times I was able to see. I had work to do And came back 90 min later and didn’t see any more rolls or courtship after observing for 5 min so I pulled them fearing they would start eating eggs. how long before the eggs hatch, and then become free swimming? Have read a lot about light sensitivity, I have a towel on the tank, how many days before Turning lights back on normal schedule? Last question is when do I start feeding infusoria after the eggs are laid in terms of days from when the spawning occurred?
  12. I am seeking some guidance on tetras! I recently purchased my first group of tetras after watching @Cory's videos with Silvertips! I fell in love with their look and their interactive behavior. I have 6 X-Ray tetra and 7 Silvertip tetras in my 40 breeder. I have noticed that two of the male Silvertips seem to bully a bit. I haven't seen any fin nipping or anything like that but they do a lot of chasing, darting at others and even seem to corral the group to one side of the tank. I have also seen two males display almost sparing behavior where they will circle each other in a tight circle and dart at the other. What can I do to help curb this behavior? Or is it common? Some possibilities I thought of was maybe larger school? Or more females? I am worried about some of them getting stressed and in-turn getting sick from being in this environment. I appreciate any advice you can give! Thanks! *Additional Potentially Helpful info* Temperature 77.2, PH 8.2, Ammonia 0ppm, Nitrate 0ppm, Nitrite 0ppm, GH very hard, KH 160ppm, 40 breeder with two medium Aquarium Co-Op sponge filters. I feed a mix/rotation of Hikari Vibrabites, Xtreme Spirulina flake, Hikari micro wafers, micro pellets, Tetra color flake and Hikari freeze dried bloodworms.
  13. Just gone through some water quality problems which are hopefully now addressed looking into the future (I had issues with PH dropping and disrupting the cycle of the tank massively.) 2 blue king tetras have showed symptoms of what I believe is Columnaris? I've moved these guys over to a small hospital setup I have going and have begun dosing salt at 1 tbsp per gallon as I'm told Columnaris can kill very quickly so I didn't feel there was much time to mess around. (I had previously hoped to try a Methylene blue treatment, but in the end I ended up water changing 90% of that out as the fish were hugely distressed and franticly darting when it was in there.) It's been around 2 days now in the salt, and I do believe that I've seen small cotton like threads come loose from the affected areas of the fish. As you can see, there's also quite a clear black outline forming around the affected areas which has become more prominent as the treatment continues. Is there anything more I can do to help these guys as a UK resident? We cannot get antibiotics legally. I'll take any advice and help I can get as I'm very attached to these guys and want to do right by them. Thank you!
  14. Hello everyone. New here, but it seems like a decent place. Recently purchased a few of these... They were advertised as “cherry barbs” but, even though they are juveniles, I have my doubt that this is in fact accurate. Thoughts?
  15. Woke this am and noted something white hanging off the side of my 3 year old Tetra. He was OK yesterday, but noted he was swimming around a plant and not schooling with the other 4 tetras in the 75 gallon tank. Have 8 cory pandas, one pleco, one oto and one angel. Took video and when I came back downstairs the white thing had fallen off and now there is just a whitish area. The area doesn’t look swollen. Perform water changes every 7 to 10 days depending on my nitrates. Never allow my nitrates to reach over 40. Ammonia – 0 Nitrite – 0 Nitrates – 40 pH 7.0 Recently bought java moss, noted two bladder snails and had some bearded algae, but the bearded algae is gone now. Back-story on my tetra. My niece, who was a flight nurse, died January 2019 and this was her only fish left. This fish means a lot to me and any help would be appreciated.
  16. Hello! I've got some voracious Red Eye Tetras that just nibble on EVERYTHING. Any small leafed plant - gone in a matter days. Countless micro swords, small crypts, and wisteria gone. My poor anubias can't grow new leaves because they eat the darn thing before it can even grow. The only thing they don't seem to touch are my lilies, larger, established crypts, and java fern. They chew on my amazon sword but it seems to grow too fast for them to make a sizeable dent. What are some of your recommendations other than those as to "non-edible" for the future? I've tried feeding a ton to slow them down, tried feeding boiled spinach regularly, no stopping them. Crazy buggers.

  19. I had 7 Black Skirted Tetras for several several years. One developed what I thought was fin rot. I put all the tetras in a 10 gallon hospital tank. I tried everything but the fin didn’t get better or worse. They stayed in the hospital for months. One morning 5 were dead and already decaying. The 2 remaining are perfectly healthy. I’m scared to add them back to the community even after 2 months. Now do I need to get more so there will be a school and less stressed. I feel bad if I don’t but I’m not sure if I want tetras for the rest of my life but hate to give them away since I’ve had them for a long time.
  20. Hoping I wasn’t going to have to post here, but just lost 6 of my 7 cardinal tetras today and the 7th is likely terminal and not sure on my next steps. A little bummed about the die-off as its suddenness was unexpected. As I am not sure what data is helpful, so I have included water params and significant events as it is a new tank. Tanks is a 20 long planted tank with following water params pH: running 7.4-7.6 Nitrates: 10-30 ppm Hardness: 10-12dgh Nitrite: 0 Ammonia: 0 KH/Buffer: 8-10dkh Water Temperature: 76F I have been running weekly checks of the above water params with a liquid kit. After I added the fish I added daily checks with Co-Op test strips and there were no elevated levels of ammonia or nitrites and the other values, excluding Nitrates, remained the same as well. Nitrate levels did vary a bit due to fertilizer additions and plant consumption. In terms of timeline and significant events I had the following: Mid-February set up tank with hardscape, eco-complete, Fluval 30 filter tweaked with course sponge and no carbon, heater, Stingray on a timer, and a small sponge filter with air stone. 1 March added Crypt Wendetti and Parva, Java Moss, Scarlet Temple, plus Water Sprite from the Co-Op. All but the moss died back (USPS took 8 days to deliver), but everything except the Scarlet Temple had started growing well. Water params were "good" and have been using Easy Green and a little Easy Iron. 26 March added seven Cardinal Tetras from a LFS (only fish in the tank) 29 March added some additional Water Sprite to replace the Scarlet Temple which never recovered. The new Water Sprite was and is growing very well. 3 April I noticed some spots that I took to be Ich on all the Tetras (pics attached), moved them to a 5 gallon hospital tank, and used the sponge filter from the 20 long. Temp was kept at 78F. 4 April realized I had accidentally under-dosed Ich-X (0.25ml v 2.5ml) and corrected to proper dose plus started daily 30% water changes followed by re-dosing. 4 April to 6 April fish seemed to be OK, other than spots, and were eating an alternating mix of fry food and frozen Daphnia. All fish appeared energetic and water params were consistent with main tank 7 April returned home from work and 6 of 7 tetras were dead with 7th appearing unlikely to survive. Did add some Maracyn for remaining fish as dead fish seemed to have some possible fin rot that I had not noticed while they were alive. My questions are: Did I miss diagnose (or miss treat Ich), was it Epistylis, or something else? The rapidity of death, fatality rate, and simultaneous nature seem odd. The following day after I had pulled the fish from the main tank I noticed some odd white growths (1-2mm and look like small white pills of cotton) on the moss and hair algae in the tank (pic attached). Curious what folk’s thoughts are on that? Other than being time coincident may be completely unrelated, but wanted to ask. Are my water parameters just too far outside of a Tetras required range? I had hoped to get a mix of Cardinal and Rummy-nose Tetras plus some Amano shrimp for the tank, but not sure on how to proceed at this stage as I don’t know what killed the Tetras I had. Thanks for any help or guidance, Merrick
  21. Hyphessobrycon sp. “Yellow Lapis” or the yellow lapis tetra. Interested to see if anyone has any experience with these tetras. My LFS has a small amount of them.
  22. A few weeks ago I got 11 cardinals. In the first couple days I lost one. Like it just disappeared. Then I lost another after 3-4 more days. Now I lost a third one yesterday. The tank is in the kitchen so if they jumped I'm pretty sure I'd find a body as there's not a lot of places for a body to hide. I do have a lid but it doesn't cover the back 2". I've not seen any nitrogen spikes, my nitrates are 5 before fertilizing. I don't have pets other than fish. Is there an explanation I'm missing?
  23. A few weeks ago, I posted a topic on here and we diagnosed that the white stuffs on the fins are some type of Stalked Cilliates parasite. So I spent 2 weeks treating the tank with Paraclancse and IchX (after a couple weeks of salt treatment then Maracyn and IchX) but I got very little result. One of them did get better but for the other three not too much. Their tail fins are somewhat rotting as well. They are still super active and agile. Anyone know anything about this or anyways to treat this? I have attached videos of them. Not sure if they are very clear like the last post. They are super camera shy https://imgur.com/gallery/PLkO82J
  24. So I have a 75 gallon heavier planted tank with cardinal tetras, ember tetras, and some rasboras. Want to add to it and had some suggestions of rainbows and Bolivian rams. Would Bolivian rams and rainbows work with my current fish? I know anything is possible I’m just nervous of getting them and waking up and all my tetras and rasboras gone with the rams and rainbows with full bellies . I guess I’m looking for possible reassurance that this combination is doable 😂
