I released 6 females into my 10g on thursday. At first there was mostly chasing and hardly any bites.
Today I came home from work to find that one of the girls (who seems to get chased and bit more than the rest do) has had her fins torn pretty badly. I isolated the fish that I think is responsible. (she chases and bites most of the other girls as well, just not as bad)
Now I don't know what to do.
Should I take her (the biter) out of the sorority permanently and replace her with a new fish? Give it time and reintroduce her (if so how long should I wait?)? Let her go back in now and let them all figure out the pecking order?
