Algae Hermit Crab or Rock Hermit Crabs are the perfect algae eaters and scavengers for the reef aquarium. They are always busy picking at algae growth or cleaning up any waste food in the aquarium.

Livestock arrives in and out of stock very regularly, depending upon availability of the item from the source. The more rare and expensive items are often difficult to hold in stock, and can take time to source, so we generally require a deposit to locate and purchase the extremely rare items

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.
