I have a male blue crowntail and he has this whiteish stringy stuff on his fins. its hard to see, but its def. there hanging well below his fins. i have been treating him with maracyn as it says on the box, and it helped for a little but now the white stuff is back. i had one die last week and i think it was the same problem so hopefully i can keep my crowntail alive. any advice?
