The oscar is the tank a#%hole, for lack of a better word. He's like most oscars in the fact that he grows like a weed, eats like a pig, and has the temper of an africanized bee. The only diffrence is he dosen't kill. Unlike other oscars I've had this guy dosen't have that killer instict for some reason. He actually seems to have respect for the other fish in the tank. As long as they don't get him too choked.
