Im sorry to hear about your fish. i think it was prob. getting beat on but I dont know for sure, Im not going to lie I dont really know Oscars to well but I know what not to do with them. If I were you I would think about getting rid of the next smallest one because from what I heard that will be next. you guys should leave Bob alone everybody on this forum has told him the exact same thing at least 300000000 times. If he chooses not to listen thats fine, just be happy they are not your fish. And Bob please for the sake of newcomers dont give advice about stocking. Stick to the other things like feeding and decorating, your tank does look beautiful Im not going to lie about that so you must be good at maitnance and such so you wuld be excelent on advice for those things. this is going to be my last bob post lol :dance2:
