Species description
Geographical Origin and Habitat: Distributed throughout the tropical western Atlantic, from Florida to Brazil, on coral reefs and rocky shores.
Taxonomy: Classified under the Diogenidae family. A small hermit crab with asymmetrical claws; the left claw is notably larger.
Social Behavior: Peaceful and active scavenger. It spends its time crawling over live rock and substrate, feeding on organic debris and algae.
Coloration and Sexual Dimorphism: Features dark brown or maroon claws with bright orange or red tips. Sexual dimorphism is not externally visible.
Care, breeding and tankmates
Tank Setup: Suitable for nano-reefs of 10 gallons or larger. Provide plenty of rocky areas and empty snail shells of various sizes.
Diet and Feeding: Herbivorous and detritivorous. Excellent at consuming nuisance hair algae and leftover fish foods. Eats pellets and flakes.
Water Quality: Demands standard marine conditions: pH 8.1-8.4, temperature 22-28°C, salinity 1.023-1.025, and zero copper levels.
Compatibility and Tankmates: Reef safe and harmless to fish. Ensure enough empty shells are available to prevent shell-stealing from snails.
Aquarium Breeding: Spawning is common. The female carries eggs under her body. Larvae are pelagic and do not survive in standard home aquariums.
Risks and Diseases: Starvation or shell fights if empty shells are missing. Sensitive to copper treatments and sudden specific gravity changes.

- Richiede calcio e iodio per favorire la muta e rafforzare l'esoscheletro.
- Molting
- Muta periodicamente richiedendo piccoli gusci vuoti per alloggiare il corpo.
- Reproduction
- La riproduzione non ha successo in acquario domestico a causa della filtrazione delle larve.
- Compatibility & tankmates
- Pacifico con pesci e coralli. Può competere con le lumache per i gusci vuoti.
