After I saw him like that I went to put up my water change stuff and came back and he had already pooped... But I have seen the apisto poop and it's just a long pellet that stays together if that helps any... I tried feeding today and he attacked the bloodworms cube but after he got 1 it took him a while to eat it (unusual) and while I was gravel vacing the snail shells kinda get sucked up and he attacks them so hopefully I'll get my pond snails I ordered in and he'll eat those.
