About Me

  1. Hi all - what are your thoughts about putting in 10 red cherry shrimp in a 15 gal with 4 otos? I supplement the existing algae with a daily algae wafer, and the otos seem to be doing good with that. That said, I had no idea how voracious the otos were with respect to algae!!! They crushed all of the algae overgrowth in a matter of days. Are the shrimp the same way? The tank is planted (Anubias nana, Pogostemon Stellatus Octopus, and Staurogyne Repens), and also has a few white cloud and glow light tetras, so they get flake food. Would love your thoughts and wisdom… thanks!
  2. I purchased a group of oto and in the process of transferring them to the tank several managed to get their nose stuck in the netting. I've given them an hour to work their way free and tried gently moving the net and tugging the fishes but they are still stuck. Any suggestions as to how to free them ?
  3. Fresh vegetables seem to do wonders in breeding them; as you can see in the pic the fry are constantly on/around the zucchini, squash, spinach, and mulberry leaves I put out. It's a community tank, so the shrimp like them too. I noticed and got footage of the oto breeding dance on 3/15, so the fry in the attached pics are roughly two months old. I have seven surviving that I have counted concurrently, but there may be more hiding out.
  4. I had about 2 dozen ottos in planted community tank that, over the course of about year, all disappeared. I started feeling guilty that perhaps I neglected feeding them enough, even though I have been feeding Repashy super green somewhat regularly. I thought maybe they were stressed by all the other rambunctious fish (lots of barb species). Or maybe they are just as fragile as people say. I thought -- am I really just using these like a disposable cleanup crew? Clean up the algae outbreak, then good luck to ya, you're on your own. However, in the middle of last night, I had to grab something from the room where my aquarium sits. When I turned on the light, there were all the ottos -- I quickly counted at least a dozen -- lounging around on sword leaves, manzanita wood branches, hanging off the glass. What gives? Why do they snub me all day long and then wait till I'm fast asleep to come out and party? (Hmmm . . . come to think of it . . .where the heck are my corys? I know there is at least 2 dozen of those ever multiplying little buggers in there!)
  5. Hi all, new member here! I was just wondering, I've read and been told that it is common for otocinclus to die within the first few weeks of arriving home. I know on Aquarium Co Op the reason stated is that once otos are starved beyond a certain point they lose their appetite and then they're as good as dead. However, another reason I've heard online for this is that otocinclus rely on a symbiotic relationship with gut bacteria, and during shipping (slash time at neglectful pet stores) the gut bacteria can die off if they're starved for too long. So apparently even when they come home and they're eating the food you give them, since their gut bacteria died off they can't actually digest the food they're eating, and they die. They're full but at the same time they're unable to absorb any of the nutrition, so they starve and die. I have found lots of people on forums and care guides stating this, but I've tried and tried and haven't found any scientific papers or been able to find who actually discovered this about otos. I was just wondering if any of you know of the source of the knowledge that otocinclus rely on a symbiotic relationship with a bacteria in their gut to digest their food? A lot of you are so much more experienced than I am, am I just looking in the wrong places? At this point I'm starting to question whether someone just made this up to account for mysterious deaths in the first few weeks of bringing otos home, and then it just caught on because people accepted it at face value.
  6. @Colu Full QT Trio plus GC/PC follow up 3 weeks later. 2 have been in the main tanks for several months. Just thought they were getting fat. But now I question what's happening. So this guy is back in QT and just dosed his 2nd dose of Levamisole. No change. What do you think? Disease, fat? That spot has me worried.
  7. Today I was researching otos diets so I could buy the right repashy for them. I'm hoping it will help with getting them to spawn. While looking them up I learned a few things. 1 they are capable of breathing air which is pretty awesome. 2 some species of otos not only school with corys for protection but have evolved to mimic their coloration and patterns. One example is Otocinclus Flexilis which mimics Corydoras Paleatus. I looked up pictures and it's pretty awsome! I thought others might think so as well. I keep C. Paleatus and have had them spawn a few times but now I really want O. Flexilis to go in the tank with them. I've never seen them available in the hobby though. Has anyone seen them for sale?
  8. I have had my fish for about 2.5 weeks. I have a betta, some lamb chop rasboras, and three otos. Everything has been fine except that the last few days I noticed that one of my otos rarely moves and just lays around on the bottom of the tank. It is alive as I see its gills move and I have seen it move position in the tank recently. However, I don't think it is eating. The other two have large, round bellies and are constantly eating. This one has a sunken in belly (see oto on top right in the pic). I have algae growing on the plants in the tank and I put in algae pellets for the otos every few days. Any idea why it won't eat and what I could do to get it to eat? TIA! I just did a water change (it was time), but when I checked my water parameters yesterday things looked fine.
  9. Hi everyone, I just started a new 75g tank, and am back in the hobby full force after life got in the way for awhile. Overall, I found the information on the site and aquarium co op videos very helpful, and the customer service has been good, especially Candi dealing with a shipping issue we had. I setup the tank with plants from some of my other tanks and ones purchased here. Once I had some algae, I added a small about 6 otos and 6 corys, as well as 2 small SAE. Now at least of my two of my Otos have some sort of white markings, almost like a bite was taken out. It is white, but definitely does not look ick related. The odd thing is the behavior of the fish seem perfectly normal, they are cruising around on the leaves and glass and have taken out the little algae I had with relative ease. The tank has no ammonia, no nitrite and very little nitrate, I've tried to let the plants do the work and help cycle the tank. I'm wondering if I should treat, or let them be and see if they heal. I'm a little stumped, and I a little disappointed this has come up so quickly, when trying to do everything correct. I'd rather not medicate a new tank and disrupt anything. Any advice and thoughts are great appreciated, Thanks.
  10. I got three Otocinclus vittatus on Saturday and they seem to be doing well so far. They are from a person who bought them to help his diatom problem and they did the trick. Now I have them because I think their personalities are great and they have the added bonus of being algae eating machines, from what I hear! I have them in a 16 gallon with a lot of diatoms and minor string algae (it's a month old set up). They haven't taken to eating any diatoms yet but their bellies are plump and they are active as all get out. Do you think they may just be full and that's why they aren't eating the diatoms? Could it be that they haven't fully adjusted to their new digs? They were eating the Xtreme Nano I put in for my Panda Corys so I know they've eaten a little bit. I just want to make sure they'll eat the diatoms and have plenty of them! TIA
  11. The first inhabitants are in! So excited to watch them grow! 6 Corydoras panda and 3 Otocinclus sp. All are doing well (just put them in on Saturday). Corys are hiding in the back left corner most of the time while the light is on but I'm sure they're just getting use to their new home. Otos are zooming around like little jets and enjoying themselves. So excited to start my journey in fish keeping!
  12. I got some random algae based food to feed to my oto (right now it's only having algae, and occasionally cucumber and spinach). He didn't even get to taste it before my shrimp and betta completely devoured all of it, which led to overfeeding the betta. I'm now looking for a replacement for this food, hoping there's a product available for international shipping with 100% veggie contents. I found something I can get locally called 'JBL Spirulina' but unfortunately it contains about 12% fish ingredients, and I'm afraid that's still too much of it so my betta will see it as food as well. I'm wondering if anyone can suggest a product based on experience? Is it safe to just get spirulina supplement tablets you can find in iHerb and feed it to my fish?
  13. Greetings! I bought 7 otocinclus on may 28th and put them in quarantine with the med trio. After a week, one developed a bad case of fungus and sadly passed away. I retreated the while tank with the med trio. The 6 others seem to be fine - I see them grace on plants, substrate, glass. And they also eat the Hikari algea wafer (that is what the store was giving them). I will soon introduce zucchini and repashy very stinky soilent green! How long should I leave the wafer in? They seem to ignore it until 24 hours later when it’s all mushy... Are they sensitive to Flourish excel by Seachem? I usually fast my fish one day per week. Is it ok to do it with Oto as well? I read they often die of starvation so I want to be sure... I give them one full wafer for the 6 of them, is it too much? Should I wait until they finish it up before giving a new one? Usually I will siphon after 24-36 hours but they seem upset because that’s when they wanna eat it! Is seachem garlic guard good for them as well? I try to soak some food or add it to the tank about once a week. some of them have really long think string of poop. Not white, it just seems like poop that won’t fall. Constipated? Too much food? Thank you! Here is a picture of their belly. Is it round/well fed type of belly?
  14. Hi guys, I currently have 4 otos in the tank for a month now, and 1 of them has these bumps on the gills (below the mouth). I noticed this guy likes to isolate himself from the rest most of the time and hides a lot. I just noticed these bumps on the gills. Does anyone know what these bumps are? and how should i treat it? thanks!
  15. I hate creating these posts. I have a 20 gal tank that had a diatom algae overload. I got two Otos to help manage it and maintain a clean tank. 2 weeks ago one Oto died unexpectantly and I just found my other one dead this morning. My water levels have stayed pretty consistent and I try to check their stomachs to see if they are nice and full but after the first one died, I noticed that the remaining Oto was hiding a lot more which made sense. But it made it difficult to see if he's been eating. I'm trying to look for factors that could affect this. Lack of food could be one of them. It's possible they weren't eating (even though there is algae in the tank but maybe not what they liked). This worries me because I have a Siamese Algae Eater as well and I really dont want anything to happen to it. The only other thing I am noticing is my ph is a little high (7.6 on "low ph test and 7.4 on high ph test). My water from the sink is at around 6.8 so something in the tank is causing it to rise, I think. Everything else for my water is really good. Which is frustrating because I do my best to keep my water great for the fish. I just don't know what else could have caused them to die all of the sudden. Thanks for the help/advice.
  16. Hi all, new here and I tried to find a similar post so forgive me for starting a new one if there was a more appropriate place to be- posted on the introductory page a bit about what I have as far as tanks/equip/fish etc. When I started my 20 gallon I just wanted a peaceful community tank with fish that had similar parameter needs of course and I didn't want reproduction, so I avoided live bearers and "easy breeders". I ended up with 10 Harlequin Rasboras and 7 Otocinclus. Well about 6 months into my endeavor I now have 25 baby catfish and counting. I know some have fallen prey to the Rasboras which is ok, that's nature, but I've managed to contain the 25+ in a floating breeder box (boy am I glad I got that for "back up" plans). I seem to catch 1 or 2 daily in varying stages of develoment. Of all the hours and hours of research I did I didn't look into this because I never thought I'd be able to breed what is sometimes called on the internet an "intermediate level" breeder: now what?! I started another 20 gallon which I plan to likely house my Rasboras and I'll up the number of Otos in my well established algae covered tank where they bred- I have 1 friend who also keeps fish and she's taking a half dozen. This isn't likely to stop happening so can anyone give me ideas on how to rehome fish? Thank you in advance for your ideas!
  17. Water parameters: Nitrate: 10ppm Nitrite: 0 Ammonia: 0 GH: 150ppm KH: 40ppm pH: 6.8 Water Temp: 78°F 29 gallons: Platies Otocinclus Red Cherry Barbs Kuhli Loaches Hey everyone, It seems that one of my Otos has an eye injury/infection, but I’m not sure exactly what it is. I originally thought this otocinclus was dead when I first saw it, but when I put in the net to scoop it out it started moving around, so it seems to be alive and eating algae off of one of my plants. If anyone has any insight or advice, I’d love to hear it. The right eye area is the only place I can see with damage.
  18. Has anyone had otocinclus in very hard water and high ph. My water is 20dgh, 10dkh, 8.0ph. I've always wanted them but stayed away because they are wild caught and from soft water. I was just curious if anyone had pulled it off successfully?
  19. All my Otos are plump but this one looks like a tabpole! Should I be worried?
  20. My aquarium is about a month old now and is fully cycled (not seasoned, mind you) I do have a good carpet of diatoms and heavy diatoms on the wood piece. I want to get Otos because I love their behavior and looks and purpose but was curious if I should clean up some heavy diatoms in my tank before getting them in a couple weeks. Or, should I leave the diatoms heavy so the otos (and corys I am going to get a well) have some good food sources?
  21. When I started my fifteen gallon tank, I decided to do a fish-in cycle. I couldn't source enough lava rock, so I only planted on one side. With the half-planted tank, I let it run for a month before adding my first five ember tetras. Of course, they were watched, like a hawk, and water was tested daily. After a week, four more were added. I floated the bag of new fish and did something else, for a while. When I went back, to add tank water to the bag, I found both groups of fish with their noses pressed against the plastic barrier. A week later, four more were added; with the same behavior shown. Next, came the three otocinclus. I acclimated them and released them into the tank. The little embers swam with the otos, from the very beginning. They were welcomed without any fuss; even though they were much larger. Then, I added five shrimp. When they were released, the embers all ran and hid. It took them two or three days to get over their fear of the strange, scary monsters. Lots of fun!
  22. Hello everyone! I am wondering if Bristlenose and Otocinclus catfish could live together?
  23. I have a 5g QT set up. It's been running since November. I sometimes use it to house fry, treat a fish, but mostly it just grows out plants for me. So I purchased some ottos 48 hours ago. They looked okay, got home settled them in & the next morning at least 2 have spots on them. I have 4 ottos in my 29g & was just purchasing a few more to enlarge their school... My 29g looks pretty empty. I purchased Aquarium coops med TRIO so I have ICH-X on hand. The spots are white and mostly on fins, a few on body. I've had ICH before on mollies when I first started & did not know what it was or how to treat it, & it killed all my mollies years ago. I remember exhausting myself with WC, Salt, and herbal remedies petco gave me that didn't do anything. -How do I dose ICH-X in a 5g with scaleless fish? Should I use half doses? - I started by slowly increasing my salinity, right now it is at 1/2 teaspoon per 1 gallon. - My water conditioner is Prime, is it safe to use Prime, salt & ICH-X together? The only other additives are Easy Green liquid fertz & two Seachem root tabs. - lots of anubis & RRF plants Live in here. -No, my heater is not adjustable. Its a 100W aqueon 78° preset Parameters are: Nitrate: under 20ppm. Nitrite: 0. Ammonia 0ppm. Chlorine 0. PH: 7.4. GH: between100-150ppm (not degree) KH: 60ppm. Parameters have been the same & stable for a long while now.
  24. 40 gallon community tank, very heavily planted with shrimp, snails, glofish and Otos Ammonia 0, Nitrites 0, Nitrates 5, GH 10, KH 7, PH 7.5, temp 77 F, Light Fluval 3.0 planted setting with night time off. They are fed Tetra Flakes, Hikari Blood worms, Bacter AE, algae wafers from Hikari and API and xtreme. I recently tried to get rid of black beard algae so I dunked my infected moss balls and plants in peroxide, then rinsed and put back in tank, well of course my moss balls died and looks like they grew fungus. Now I had one Oto die with cotton mouth on the day I started treating them with Maracyn and ParaCleanse. After 4 days, I am losing another Oto that it is spreading on his tail fin. I started adding Ich X starting today. I will be removing the moss balls. I just wanted to go through one full round of meds first, then I was going to clean during a water change and repeat another full round. My question is maybe should I be using other meds, I keep seeing articles recommend Maracyn 2, I guess the regular Maracyn only affect gram positive bacteria while the Maracy 2 attacks both the gram positive and negative which is the more common type. Thoughts? The infected Otos are fairly new to us but I quarantined them for three weeks with all three meds before I added them to my tank. I think its my dead moss balls that created this problem a month later and maybe the fact they don't have as much algae since the tank was thoroughly cleaned recently in the process of ridding the black beard algae. Please advise. Thanks Elizabeth
