So far I have been feeding Atticus in a separate container - cardboard box with a lid, and he has been eating very consistently. The reason I do this is because he sometimes creates a bloody mess when he eats, and it's easier to throw away a cardboard box than to change out substrate. It's also a good time for me to spot clean, change water, etc. Someone pointed out that my strategy may become more inconvenient as he gets bigger, but I will keep using the feeding box until that happens.
