Aquarium suitability - Reef compatibility – Yes Captive care – This crab has two symbiotic Bunodeopsis anemones on its claws. It uses the anemones to filter feed and in return takes care of the anemone. It will usually hide in the rockwork so this crab can be best seen in nano tanks after the lights are out.
