corydoras

Hi, I currently have a 10 gallon tank with some green and peppered cory catfish in it. One of the peppered cory cats looks very skinny to me compared to the others. It’s a little less active, but still more or less acting normal. I’m worried it’s in the early stages of some kind of disease, am...

I got 4 Panda Corydoras for my sister yesterday, 3 of them are around an inch long, very nice fish. I love watching them huddle together, then explore the tank together and occasionally shoot up to the surface and straight back down to the bottom. They look like they're having so much fun. They...

Hi all, I have a community tank and my albino cories have decided to lay eggs. This was not intentional but I am uncertain if they are fertile or not. If they are fertile, I would like to try and hatch them. The eggs on the glass appear to be relatively clear/white (therefore unfertile I...

Hi all I will soon be offloading the 5 Oto's which I've had a month of so. Firstly, because they have done the job I initially got them for, but mainly because the physical waste they produce. Between them it's astonishing for such a small fish. I can't keep up vacuuming it out! Anyway i'm...

I currently have 3 corydoras, a dwarf gourami, and a ctenopoma. They all get along fine so far. We are hoping to get some larger fish because our ctenopoma can get up to 6 in and will eat whatever fits in their mouth. I was thinking an angelfish and maybe a gourami or a few rams (ones that...

A short while back someone asked about Corydoras catfish poisoning themselves during transport. Just this week I came across an abstract of a study very recently undertaken to identify the toxin(s) and provide more information on the process. Here is a "poster" with some data from this study...

Hi! Following the suggestion of my friend RR, I'm starting a thread about my journey for my first biotope tank. I'll update this when I have new dev going on for this tank. (Or if something change in my 32 while my Corys wait on me for the 55) Currently I got a 32 gallon tank with 5 peppered...

Hey Guys, I've recently bought two pairs of leopard endlers in the aims of starting a nice colony, however I am wondering whether corydoras pose a threat to newborn fry? As from what I gather from research is that some say they do and some say they do not. Thanks for the help!

Hey there, I'm completely new here, and to keeping corys. I recently purchased two corys from my local pet shop, but there was no specific label on them. Can anyone please tell me what kind I have, so I can get more for a school? Thank you so much

I came across this study and thought some may find it interesting.  As it mentions at the start, the purpose of the adipose fin--which is present on Corydoras and many catfish, as well as most (but not all) characins, the salmon, and some others--has generally been thought vestigial and without...

Hey.   I'm planning a new aquarium. I want to know which kind of corydora catfish I should go with. Bronze, or peppered? There will be a lot of plants, and tank mates. Guppies, tetras, and danios. I want a fish that will be active, friendly, and fun to watch. Thanks.

I have read up on Google alot on this BUT I need clarification I cant seem to find!    -To my understanding fertile eggs turn a light beige or tan eventually? and non fertile have a white center and turn white in the first day or so? (this Ive seen alot)    How long after being laid do they turn...

Hello Fishforums,  

Hi there fish folks....   I installed 4 skunk corys in my 125l fish tank 2 weeks ago....   The tank has now been running for about a month with a few guppies and a plec.   One of the skunks appears to be losing its colour and not as active as the other 3 - please see pic.....   The ammonia in...

Hey guys!   This is my first time writing on this forum. I just wanted to get your opinion on one of my panda corys.   About 3 weeks ago I noticed one of my corys has a rounded pale spot close to its anal fin. I honestly have no idea what it could be. Maybe eggs?!? I looked all over the internet...

Hello everyone, new to fish forums but not to aquariums. I have 7 zebra danios, 2 Cory cats, one brittle nose, male half moon betta and a female paradise gourami in a planted 20gal tank. I first notices that my zebras were having trouble breathing and hanging around the surface. I investigated...

I have one corydoras has been covered with white thin films for weeks., some lesions. Then, red belly developed. I have 55 gallon and other fish, some scaleless, who are/were till medications. Despite all these skin lesion, the Cory appears to be active and have healthy appetite. I started...

Request Help   One of my two false bandit corys (corydoras melini) can't keep balance in the water, and frequently ends up losing balance and ending up on his side or upside down. He can right himself, and swim about normally, until he stops, at which point he has the issue. Tank size: 30cm x...

Hi all I recently got some corydoras (trilineatus) but Im having some trouble feeding them. I've got some sinking food that they really like and while I think they are getting enouh to survive my greedy harlequins are eating so much of it they're getting really swollen stomachs and I'm worried...

Hi all I was wondering about the various species of corydoras in relation to high pH.   Sorry if this is a repeat topic, but if it is available, I couldn't find it easily, and though I've touched on this question in some of my other threads, I was hoping for some more direct and detailed answers...
