One of my twelve Black Phantoms appears to have been pushed out of the group and when he isn't being chased, hangs out in the corner looking decidedly stressed. Is this just the way it is with these? I'm guessing having some females would help?
Yeh I think that's a possibility, he's eating ok - i put food close to him so he's not having to fight for it. Tank is doing ok water parameter-wise so, perhaps he's the dodgy one of the dozen I boughtCould the fish be sick? Ive heard some reports of fish behaving like birds in the sense that a member of the group that is weak/Ill gets pushed out and "left to die". I don't know if that is characteristic to tetras though
