Hidden Hermit (small)
The Hidden Hermit Crab (Calcinus latens) will eat hair algae and scavenge in your aquarium. Grows to inhabit shells about 1.5 inches long. Hidden Hermit Crabs are reef safe around corals, but may attack snails and other hermit crabs for their shells. You can reduce the tendency for this behavior by having plenty of empty shells for them to move into. As adults they would need our medium to larger hermit crab shells. These hermit crabs are imported from the Pacific Ocean, and range from the Philippines to Hawaii.
