So my Oscar died this morning couldn't figure out what was wrong with him. He looked lethargic and act like he couldn't swim layed on his side. He would get these spasms in his tail and then bang his head on the lid as if he were trying to jump out. ...would not eat. Sad I had him forever. I want to get another oscar but am afraid want to know why he died before I try another Oscar anyone have an idea what it might have been???
