Banded Eye Hermit
The Banded Eye Hermit Crab (Paguristes tortugae) will eat hair algae and scavenge in your aquarium. Grows to inhabit shells about 1.5 inches long. Banded Eye Hermit Crabs are reef safe around corals, but may attack snails and other hermit crabs for their shells. They seem to have a preference for Astraea and Murex species 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 native to the Caribbean.
