I've read somewhere that fish will eat themselves to death. I always thought this to be true up until a few years ago. Today I'll feed my fish up to 4 times a day. I have a 125g with 3 Oscars and a 20 wide that I'm growing out feeder comets in. I'll feed both tanks up to 4 times a day. When I overfeed (happens rarely) the fish just seem to eat there fill and let the rest float at the top. The rest gets eaten over the next hour or 2.
So back to my original question. Will a fish eat itself to death?

,,not on 1 sitting any way,,but i reckon if you overfeed a lot your fish would have health probs just like me or u goin to mac every day 
Also I think comets can be beautiful fish when there big. One of the 2 big ones I have is around 7" and looks damn nice!
