The Staghorn Hermit Crab, Manucomplanus varians, otherwise known as the Antler Hermit Crab or Coral House Hermit Crab, looks awesome. They have created their house out of a branching shell. They are best housed in tanks with moderate light and flow, a deep sand bed, live rock, algae, objects for climbing, and other shells just in case. Be sure the tank is not overcrowded. If there is not enough natural food in the tank be sure to supplementally feed the Staghorn Crab with brine or mysis or other carnivorous preparations.
