Species description

Geographical Origin and Habitat: Western Atlantic Ocean, distributed along the coasts of Florida, the Caribbean, and Brazil. Typically lives in areas rich in coral rocks and sheltered sandy crevices.

Taxonomy: Belongs to the family Hippolytidae. Features a robust protective exoskeleton with claws developed for defense and burrowing. Size up to 4.5 cm.

Social Behavior: Predominantly solitary or gregarious depending on shelter availability. Plays a crucial ecological role as a scavenger.

Coloration and Sexual Dimorphism: Coloration varies from brown to bright red. Sexual dimorphism is not highly pronounced externally, except for abdomen shape or claw size.

Care, breeding and tankmates

Tank Setup: Requires a reef aquarium with plenty of live rock. For hermit crabs, it is essential to provide empty gastropod shells of various sizes to support growth.

Diet and Feeding: Omnivorous. Feeds on detritus, fish parasites, and leftover food.

Water Quality: Standard marine values: temperature 22.0-27.0°C, pH 8.1-8.4, constant salinity, and absolute absence of copper in the aquarium.

Compatibility and Tankmates: 100% reef-safe. Compatible with almost all peaceful tankmates. Avoid predatory fish that feed on crustaceans (e.g. puffers or lionfish).

Aquarium Breeding: Simultaneous hermaphrodite. Releases pelagic larvae that rarely survive in tanks with active filtration.

Risks and Diseases: Molts periodically. During this time it remains hidden under rocks until the new exoskeleton hardens. High sensitivity to heavy metals (copper) and sudden osmotic shocks.

Calcium and minerals
Richiede calcio e magnesio a livelli di barriera per supportare la muta.
Molting
Muta periodicamente. Durante questo periodo rimane nascosto sotto le rocce fino all'indurimento del nuovo esoscheletro.
Reproduction
Ermafrodita simultaneo. Rilascia larve pelagiche che difficilmente sopravvivono in vasche con filtri attivi.
Compatibility & tankmates
Tranquillo e reef-safe. Ottimo pulitore di parassiti per pesci di barriera. Evitare predatori.
