When I first got my (adult) bimac a week ago - he was happy to eat frozen clam the first day and frozen shrimp the second day ... Then he started to refuse them ... So I was feeding him living ghost shrimp for a couple days .... Then he started refusing those too so I gave him a medium sized hermit crab which he happily ate. I can't really afford to give him a hermit every day ($7) ... so I bought some living clams in Chinatown for him and put them in the tank. I'm not sure though if he is capable or even interested in eating the clam or if it's just another item he will pull in as part of his "fort". Do other people feed their octopuses living clams? Does anyone know where I can buy medium sized hermit crabs that aren't too expensive? How can I get him to go back to eating frozen food?
