My newly purchased krib (yesterday I purchased) is in a 55g tank with a blue kenyi, a female soulosi, and a red zebra.... I looked at him today and he wasn't moving much, at all. The other fish were kinda poking it out of curiosity. Then I stuck the fish net in there to see if he would nudge, or move.... He slowly, I mean slowly, pushed himself away from the net. Then I examined his closer and it appeared he had a missing right fin, I think taken away from the female soulosi.... because it was nipping it a little. Then he wasn't moving at all (but gills were) and lying sideways (I think because no fin causes him to do that) , and the other fish were poking him calmly. After I noticed it I took him out of the tank and added him to a 5g aquarium.
poor fish!
What do I do?
