Also I've found that heat helps speed up their growth rate. Their metabolisms are temperature dependent, so heat is good. I do some without heaters, and they grow about half as fast as the ones where water is 75-80 degrees.
They don't require an airstone or filtration. Their slime would just gunk up the filter, anyway. They breathe air by going to the surface.
agreed that heat speeds up the metabolism, but will dramatically reduce the life span, which i guess doesnt matter if they're going to be fed anyways. however no airator or filter, doesnt your water get stagnant?
