My corys are dying and being eaten.
I have a 29g tank with 8 corys, four green and four peppered. I also have six cherry barbs, four otocinclus, four rosy barb, and one odessa barb. Recensty I found an unknown small white fish that appeared out of nowhere. It looks like a oto but its all white.
A pepper died. I thought it was sick but its tail was eaten off and it looked barren inside. Then another pepper looked sick. I used pimafix and melafix until he was okay but then days later i found him the same way as the first one. Now a green cory this morning had its tail eaten off and he was just a hollow shell.
