Oscars are always doing something crazy or stupid, I guess that is a big part of their appeal. Not long ago my oscar was laying on the gravel his color was faded and I thought he was dead. As soon as I got up and went over to the tank he sprang to life, flashed his colors and did the "feed me dance". I went back, sat down, and he did it again, played dead. He also splashes and jumps around often.
