  1. I'm a little sad I just bought the cutest little peppered corydoras for my 5 gallon tank and now I read there should be 3. Is thAt a problem for a 5 gallon tank? With nerite snAil and betta?
  2. Hello everyone, The 95 Gallon project is progressing to the point of making some stocking decisions. Currently, there's a very cheap, very nice group of corydoras available on our local fish club auction, and they're precipitating my question. I LOVE bottom-dweller/cleanup crew fish, but I don't want to end up overstocking. Here's what I'd LIKE to do (all added very gradually. Starting with 8-10 guppies who will increase from there) -Livebearers, main focus of the tank--mostly guppies, plus a few platys and they'll increase their own population to be controlled eventually with the planned last addition of the tank: -1 Angelfish Then I'd really LIKE to add-- -Kuhli loaches -Corydoras -Hillstream loaches Too many cleanup fish? How many of each for the best behavior/balance? With a population of guppies/platys and an angel (eventually), how many of each would you suggest for a 95 gallon tank? I know the guppys and platys will carry plenty of bioload as they reproduce, so how do I figure out the bioload of the "other guys"?
  3. I got 6 corys on Sunday. They’re all great, eating, parameters good. However, one of them flashes. Should I be concerned? If so, what should I do?
  4. Ah, my Google News algorithm knows me well. Interesting article on fish scale "armor" and the trilineatus cory. https://api.nationalgeographic.com/distribution/public/amp/animals/2021/01/tiny-catfish-shrugs-off-piranha-bites
  5. I've got bronze corydoras and I've got them to breed 3 times now(at 2 to 3 week intervals). I was pretty excited when I saw the eggs as it was my first time EVER seeing fish eggs in my tank(i'm pretty new to the hobby, 1 year experience only). I spent the whole afternoon making diy breeder containers from tupperware since i read that the baby fry and eggs may be eaten and I only have one 10 gal. I also read that eggs will turn brownish if it was fertilized. You can imagine my disappointment when i checked on them the next day and they were all white. And this has been happening all 3 times. I see the catfish doing the "T" position but not quite the "T" position. I've seen many videos of corydoras breeding and I always see the male lying on the side while doing this, but mine are just on their belly. The female also isn't actively trying to get the sperm, she just normally breathes(sorry for bad description,I don't have any video footage). So I am wondering if thats the issue none of the eggs are fertilized. Is it because my catfish don't know how to properly breed yet? Idk. Much help appreciated:)
  6. Hey all! I purchased 4 Pygmy Cory cats about three weeks ago, from my LFS, they were the first fish in a new 10 gallon set up. They have settled in nicely and seem very happy! i called the LFS today to see if they had more Pygmy cats in stock and reserved 2 so i would have a school of 6. Upon returning from picking up the 2nd batch of corys and starting the acclimation process i noticed that i actually have two very different looking catfish. I now believe, after some research, that the first 4 were actually Salt and Pepper corys and the 2nd two are true Pygmy corys. I was wondering if the six of them are sustainable in the 10 gallon or if i need to return the 2 Pygmy and get my hands on two more salt and pepper corys. Thanks for any insight!
  7. Hello everybody, As you could probably tell, Corydoras are my favorite fish. Post your pictures of your cory cats here along with the species name if possible. Here I have my albino and green cories (C. aeneus), both adult and baby peppered cories (C. paleatus), and pygmy cories (C. pygmaeus.). Thanks!
  8. Hello, I have an Oscar and 4 Electric Blue Jack Dempsey's in a 125. They eat ravenously but any food that falls to the bottom they ignore. I'm looking for a good tank mate to cover the bottom third of the aquarium. I'm thinking something that would do well in a group of 6 or more would be nice, but I'd welcome any and all suggestions. Thanks!
  9. so i have some questions about cory catfish i currently have one 1 pygmy cory and I'm hoping to go to a lfs as soon as possible to get more(his friends died over the last 1.5 year 😞 ) what is a small one that would be fine in a 20 long that won't outcompete the pygmys? I have eco complete with sand in the to back left corners is that enough or should i put sand in the entire tank? will they push around lily bulbs I ordered some from the co op should i wait for them to get roots? I'm currently feeding vibra bites and frozen daphnia is this okay or should i add something else?(i have extreme krill flakes and bottom feeder wafers coming) will they eat shrimplets(fry? idk what they are called) thanks 🙂
  10. I have had 4 mail orders of Corys from 3 different reputable companies and most of my corys die. Ist order, Panda Corys -2 arrived DOA, 2 died that night and 2 lived 2nd order, 6 Panda Corys, within 24 hours 3 dead (net 3). 6 pygmy corys, 2 DOA, 2 dead within 48 hrs, (net 2) 3rd order, 8 Panda Corys, 4 DOA and 4 dead within 24 hours, (net 0) 10 pygmy corys..4 dead within 24 hours. (net 6) Others still alive right now. Petsmart trip - 8 Pepper corys, 3 DOA when I got home, 2 dead within 24 hrs - 3 survived. QT all new fish. 10 gal. Tank is solid and cycled. I have lost so much money in Corys, it disheartening. I am trying to put together a cory family of 6 for each of my 55 gal tanks. One tank has 2 poor lonely cory's and one tank has 3. 😒 Any suggestion besides my husband's "stop buying them".
  11. Last year I purchased a couple Bronze Cory and placed them in a quarantine tank for 30 days. by the end of the 2nd week they where breeding and before they where out of quarantine their numbers had significantly increased. I then moved them into my 75 gallon with a school of silver dollars hoping this would stop the breeding or the Silver dollars would keep the population down. The water in the 75 gallon is harder as well. To my dismay the breeding is more active than ever and I woke up this morning to find eggs all over the back and side of the tank. I know have over two dozen Corys and exceeding the tanks capacity. I've had Corys before and did not have this problem. Is there a way I can maintain a healthy environment for them and stop them from breeding???

  13. Hello everybody, After breeding and raising 3 gens of endlers in my 15g tank, I decided to move everything in my 33g tank and do sth different. I was thinking of having a group of 6-10 corys. The catch is that this aquarium is unheated and the room temp of the place where it is located ranges from 65 to 70 during winter (after March the minimum temp rises to 70). Is there any type of cory that would realistically cope with these temps at least until the end of winter?
  14. I have a 29 gallon tank with smooth gravel substrate and one clown pleco. Will it and corys, if I get them, be fine on it, or do I need sand?
  15. For over a year I have had this pop up every few months with my Corydora Paleatus. It starts as a spot around the head, and then it spreads. I’ve tried treating with Erythromycin and Furan 2, but I have always lost the fish. This little guy had a spot about a week ago. I moved him to the qt tank and added 3 Tbs of salt. This morning it looks a lot worse. I did a 50% water change and added 2 additional Tbs of salt (1 Tbs per 2 gallons now). I know that if it doesn’t get better in 4-5 days I should increase the salt to 1 to 1g, but is that safe for Corydora? Does anyone recognize this? Any idea how I can prevent it? I could really use some help. I love my cories but I hate losing a fish to this every few month.
  16. Every time I try to feed my corys, my betta always comes down just to get their food. No matter what I do he always finds their food and eats it. I am worried he will be sick from eating too much and my corys not getting enough food.
  17. What's up with this guy? See video below. I've had the corys for 6 months. This is my daughter's tank, so admittedly I don't pay as much attention to these fish, but I noticed one of them spinning yesterday, but I watched only briefly and thought it was just excited. Today, the swimming pattern is a lot crazier and obviously something is wrong. PH 8 Nitrates 20 Hardness 6 dGH Nitrite 0 Ammonia 0 KH 7 dKH Temperature 75F Tank is over a year old, no other fish showing symptoms.
  18. I was just wondering since I've heard mixed opinions on keeping multiple species of cories rather than just one. For instance, if I wanted six cories would 2 pandas, sterbais, and albinos do just as well as just the 6 albinos? I just want to have a good idea of what I'm doing with the bigger cory species since I've only ever worked with pygmies.
  19. This is the best pic I could get as this is the first time I have seen it, but I have Panda Cories and Emerald Cories breeding freely in my tank and there is a fry that does not look like either species. I just seen this Cory with brown markings and IDK if there is a possibility that it could have come as an egg on a plant leaf or root or if it could be a hybrid of the 2 fish?? And if it is a hybrid could it breed with it's siblings it would it be infertile?? I would love to hear about hybridization of any other Cory species as well as I have just now found out that they can interbreed sometimes.
  20. Hello everyone, Ever since I rearranged the decor in my 29 gallon fish tank (it's been maybe two months or more), my school of 5 pygmy corys don't come out hardly ever. They always are hiding under their favorite log and rocks. They will venture out a little during feeding, but always stay under or near the shadow of the log. This is confusing to me, because before I rearranged the decor in the tank, they would always be out and about. Also, I only have other types of corys, a bristlenose pleco, a pearl gourami (just added in a week ago), and some Endler's livebearers in the tank. Any suggestions on how to get the pygmy corys to be less shy?
  21. Can anyone give me tips on getting my orange laser corydora’s to be more active . I have 9 in a 55 gallon planted tank for about 6 months now , with sand and lots of wood and rock to hide . It seems I’ve made too many hiding places as I don’t see them at all unless they are eating. I have a big amazon sword and jungle vallisneria to dim the light so it isn’t too bright for them and I still don’t see them 😔 . I have to slowly creep up to the tank to even see them before they spot me and dart off. I have 11 rummynose in the tank also , am trying to get more for a larger school. Should I add more cories ? I wasn’t sure how many is too many for that size tank as they get a bit larger than some of the other species. @Cory @Cory Gang @Corycatfan
  22. Hello, I have had Pygmy Cories for awhile now and have really wanted to breed them. Any help because so far they haven’t spawned.
  23. So I got another Cory for my 29 gallon and I was wondering if it had ick it’s white spots are so small though. Also what type of Cory is it they had no tag.
  24. Hi I'm new to this forum and to aquariums. I have a 15 gallon high tank. It's been running for about 2 years. Lately my Cory catfish has been gulping air at the surface. So I figure I need to add an air stone. I just ordered a sponge filter and stone that should arrive in a few days. The tank has a hang on filter now. My question is should I run both filters or just the sponge filter? There's only 5 fish in the tank , swordfish, molly, tetra, peco and the cory. You're help is appreciated
  25. So I have a planted 20 gal long tank with eco complete and I’m looking to get 6 sterbai corydoras... I’ve read multiple sources that say you’re not supposed to gravel vac a planted tank... yet I’ve also read multiple sources that say if cory’s don’t have very clean substrate their barbels could become damaged and infected... I’m not concerned about the eco complete being “too rough” as much as being “too dirty”. Thoughts? TIA
