I need some help. Sunday I noticed my tank was leaking. I rushed to get my Oscar, Jack Dempsey, Pleco, and crawfish out and into the bath tub. My wife went got another tank and we rushed to get it set up. Up until now my Oscar had been the king of the tank. Once the tank was set up and running I got the fish in and all changed. I came home tonight to an Oscar beat to pieces. The Jack was now the dominant fish and was showing his domination by destroying my Oscar. I have removed the Jack, but the oscar is beaten pretty badly, lip is skinned up, pecs are torn and tail is terrible looking. What do I need to medicate my Oscar with? Or is it too late for her?
