What is a wild ocean hermit crabs' diet?

Answer 1

wild hermit crabs are scavingers so they'll eat things from dead fish,algee,some times fish poo and seaweed and meats.(while there domesticaded cousins eat special made food you buy a stores.)There is no such thing as a wild hermit crab's "domesticated cousin". Land hermit crabs cannot be bred in captivity, and every single land hermit crab that you find for sale was caught from the wild. Land hermit crabs can survive on the store-bought diet because they are scavengers and can eat a variety of things. It is best to also provide a variety of fresh fruits, vegetables, protein, algae/seaweed, etc. Many pet stores carry freeze-dried shrimp, dried seaweed, etc. that hermit crabs will enjoy. Keep in mind that some store-bought fish foods have copper added, which is toxic to hermit crabs, so check the label.
