Common name: red reef hermit

General information

The Red Reef Hermit Crab, Paguristes cadenati, is a popular invertebrate in the reef aquarium hobby due to its striking red coloration and beneficial scavenging habits. These hermit crabs are known for their peaceful nature and are often seen as a natural clean-up crew, helping to control algae and detritus in the tank.

Care

Paguristes cadenati is relatively easy to care for. They require a tank with plenty of live rock and substrate to scavenge on and hide in. It's important to provide a variety of shell sizes for them to move into as they grow. They are not picky eaters and will consume a wide range of foods, including leftover fish food, algae, and detritus.

Reproduction

In the home aquarium, reproduction of Paguristes cadenati is rare. In the wild, they have a complex life cycle that includes a planktonic larval stage, which is difficult to replicate in captivity.

Symbiosis

While not involved in the classic symbiotic relationships seen with anemones or corals, hermit crabs like Paguristes cadenati play an important role in the ecosystem of a reef tank by cleaning up waste and uneaten food, which can help prevent outbreaks of nuisance algae and maintain water quality.

Habitat

The Red Reef Hermit Crab is native to the Caribbean Sea and can be found in a variety of reef environments. They are often associated with sandy bottoms and reef crevices where they can find food and shelter.
