My TSN inhales food like nobody's business. he'll eat until he looks about ready to explode. my Oscars are also bottomless pits. but my Fire eels win. the worm won't even hit the water and they are fighting over them, even if I drop in 6 pieces! and they will continue to go nutters until they are all stuffed. they push the arrow and gar around at feeding time so much, those 2 don't even bother coming to get theirs until the trio of eels slink back into their hidy spots.
