There's all kinds of theories why Oscars break their heaters. Some folks think it's the light (as mentioned above), others the heat, etc. etc. My own personal opinion is that Oscars abuse everything in their aquariums, and the poor heaters are fragile and don't stand up too well when abused in that regard. My solution has been simply to use submersible heaters, and then hang them by their cord in the center of the aquarium so they can't hit anything. The Oscars nose them around, etc., but the heater only swings freely.
