I think our Molly has been seriously picked on by her tank mates. Her back tail fin is really short, and her top fin is visibly nipped. It looks like her lip has been torn to. At the moment, she's floating in a tupperware container in the tank- we've fed her, and she's gobbled it up as best she could. I think I know who's done this, but I'm at a loss as to what to do to the fish that's picking on her (and the other fish in the tank). Will the molly be ok?
