He would regurgitate his food before he would die!!! If he eat's to much he WILL regurgitate, and the nitrates will go out the roof from the uneaten food and the acid from his stomach. If imediate water changes are not done he is in a risky situation. It is ok to get a belly, just don't go crazy and give him to much. After he get's a belly wait a while to feed him again. I give mine a belly about every 2 or 3 days, sometimes longer. just depends on visual behavior patterns.
