The AlgaeHermit Crab is one of the most popular hermit crabs for the home marine aquarium.
If attacked by a predator or threatened, the Algae Hermit Crab backs into its shell and uses its claws to block and defend the entrance to its shell. The Algae Hermit is found in the inter-tidal zones.
Since they scavenge for detritus and consume nuisance algae, including red slime algae (cyanobacteria), the Algae Hermit Crab is a highly desired addition to the home reef aquarium.
If there are insufficient algae in the aquarium, their diet should be supplemented with dried seaweed.
Like other invertebrates, care needs to be taken with the use of medications.
Additionally, strict water parameters must be maintained. Be sure to accommodate their growth by supplying empty shells of various size and shape to help prevent possible aggression between other hermit crabs and snails.
