I've got an african butterfly fish which I LOVE. I feed him crickets and frozen bloodworms which are all he'll really eat, but it's getting to be kind of a hassle to keep going to the petstore a few times a week for crickets. The petstore's kinda far and I've got a busy schedule. I don't want to get a bunch of them at the same time because I'm worried that they'll be noisy and keep people awake. Could I freeze the crickets and then thaw them just before feeding? Would this harm the nutritional value? Frozen bloodworms are obviously...well...frozen, so same concept, right?
