I have had my saltwater tank for @ a month and a half and i found a half eatin hermit crab last night.. I havent really tried to feed him yet. The lfs feed him on fri and told me to give him acouple day to get use to my tank before trying to feed him. he seems to be doing good poking his head out of the rocks. he came out last night swimming around the tank , but was hiding again this morning.
