what is this?

30L tank with indian almond leaf extract water to treat fin rot. 26°C . Tank has male betta x1, 2x male endlers and 4x female tiger endlers. First set up in the first week of August 2020 but have been having trouble cycling it so ammonia levels are high, been using Prime to try and make it safe...

Caught it in a throw net, what kind do y’all think if is? Flathead?

I bought this tank off a friend just over a month ago because her brother did not want it anymore (yay for me)! Anyways part of the tank was a couple fish and one of them is this giant albino sucker... I think it is 5 years old or something. Anyways today I would like your help figuring out...

I bought a datnoid about a week ago and when I bought it I noticed some type of fungus. I figured that I could cure it with salt but I'm not sure what it is. It's definitely not ich, and I don't think it's cotton wool. What is the white thing on the end of the dorsal fin? It's kind of growing on...

So, these corys came in at my LFS, and they were labelled as trilineatus. They don't look a lot like the classic tri cory to me (or the LFS chap, for that matter), but my last remaining tri had started behaving in a manner that was depressing me; I'd accidentally pepped up my little pod of old...
