So my crabs are addicted to blood worms, when I offer them (About twice a week) they are totally GONE the next day. They will eat them before anything else on the dish. My question is, should they be given as just a treat or is it OK that they like to eat them so much and should I offer them with every feeding? Is it like candy to a child and they arent eating the "good stuff" because they filled up on worms??
