No but feed it too him raw, don't cook it next time. Fish will eat just about any kinda meat but that's not good for them. They don't have the 98.6 degree body Temp humans do so they can't break down fatty animal proteins like we can. That's why its best to feed them lean foods like fish and chicken or beef heart, stuff without fat. As the above poster said only feed it once or twice a week as a treat.
