they dont poop as often as they eat. they somehow compact down their meals into a small volume.
BTW, ive seen in the other thread that you want to breed and hatch some clowns.... with a female het clown, it would be good to get a male visual clown. not just a het clown. that gives you much better chances to hatch out visual clowns.
het clown to het clowns gives you only 25% clowns, and the rest will only be 66% possible hets, meaning they onl have a chance to actually be het clown. and these are really difficult to sell. visual clown to het clown gives you 50% clowns, and the rest will be guaranteed to be het clowns. not just possible hets. thats much better.
