Hello folks,
I'm a new user here. Started up a 37 gallon freshwater aquarium a few months ago. It's been fully cycled by now, the last readings were Ammonia 0, Nitrite 0, Nitrate 20ish, PH 7 on the dot.
It's currently stocked with 3 pearl danios, 5 zebra danios and 3 green corydoras.
Today I just noticed that one of my corys, who seems fully healthy otherwise, appears to have an extra fin. It's on his right side, directly underneath his side fin.
I have some pictures, but the links I tried to post were always showing a broken image. Mostly just curious if it's possible for the fish to have an extra fin there, or if it's some sort of possible problem.
