Most smashing stomatopods will through out of their burrow any food not eaten. Unless you have a healthy group of scavengers, you probable would want to remove it. Unfortunately, Odontodactylus scyllarus will sometimes bury uneaten food - or at least hold on to it for a long time. I've lost quite a few over the years in small tanks when their hidden, uneaten food rotted. We typically only give the stomatopods a piece of food no bigger in diameter than about a third the length of their carapace. That much food a day is more than enough to keep them growing. Usually, if an animal is nearing a molt and not going to eat, it will reject food that it has taken within a minute or two. At that point, we remove it.
