Descrição da espécie
Geographical Origin and Habitat: Eastern Atlantic Ocean, distributed along the tropical coasts of West Africa (Gulf of Guinea). Typically lives in areas rich in coral rocks and sheltered sandy crevices. This hardy hermit crab is native to the intertidal zones and rocky shores of tropical West Africa.
Taxonomy: Belongs to the family Diogenidae. Features a robust protective exoskeleton with claws developed for defense and burrowing. Size up to 2.5 cm. It has a soft, spiral-shaped abdomen that it protects by occupying empty marine gastropod shells.
Social Behavior: Predominantly solitary or gregarious depending on shelter availability. Plays a crucial ecological role as a herbivore. An active scavenger, it spends its time climbing over rocks and cleaning the tank substrate.
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. Its dark legs are accented by thin, longitudinal blue or white stripes, making it visually distinct.
Cuidado, criação e companheiros de tanque
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. Provide a tank with stable rock structures for climbing and a soft sand bed for foraging activities.
Diet and Feeding: Herbivorous/Detritivorous. Feeds on algae, bacterial film, and organic detritus from rocks. Feed a diet of detritus and algae; supplement with sinking algae wafers and occasional meaty pellets.
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. Keep water parameters stable, focusing on calcium and trace minerals needed to rebuild their exoskeleton.
Compatibility and Tankmates: 100% reef-safe. Compatible with almost all peaceful tankmates. Avoid predatory fish that feed on crustaceans (e.g., puffers or lionfish). Reef-safe and great for clean-up crews; however, they may fight with snails for shells if extras are not provided.
Aquarium Breeding: Oviparous species. Female guards the eggs inside the shell until larval release. Breeding in home aquariums is not viable due to the larval stage which requires specific planktonic feeds.
Risks and Diseases: Molts regularly. Requires constant availability of new empty shells to prevent conflicts. High sensitivity to heavy metals (copper) and sudden osmotic shocks. Copper treatments are highly lethal; ensure a supply of larger empty shells is always available in the tank.

Perfil de invertebrados
- Dieta
- Herbivore
- These crabs are invaluable omnivorous scavengers that spend their time grazing on various types of nuisance algae, including hair algae and cyanobacteria. They will also greedily consume detritus, uneaten fish food, and decaying organic matter. If natural food sources run low in the aquarium, their diet should be supplemented with dried seaweed and sinking pellets.
- Papel ecológico
- Scavenger
- They are quintessential members of the reef clean-up crew, performing essential janitorial duties across the rockwork and substrate. By continuously grazing on algae and processing detritus, they prevent organic buildup and assist in maintaining overall water quality. Their foraging activities also subtly sift the top layers of sand, preventing stagnation.
- Tamanho adulto
- 2.5 cm
- Risco de salto
- Yes
- These heavy, shell-dwelling bottom feeders are completely incapable of jumping or swimming out of the water. Their anatomy and weight confine them strictly to the substrate and rockwork. While they can climb up powerhead cords or silicone seams to the water surface, they pose absolutely zero risk of leaping from the tank.
- Sensibilidade ao choque
- High
- Hermit crabs are comparatively hardy, but they still require careful acclimation to new water chemistry and temperature. Drastic shifts in salinity are particularly dangerous and can interfere with their osmoregulation. A slow drip acclimation is the recommended standard practice to ensure long-term survival.
- Cálcio e minerais
- High
- Proper calcium, magnesium, and trace element levels are mandatory to facilitate a healthy molting process and allow their new exoskeleton to harden. Regular water changes with a high-quality reef salt mix usually provide sufficient elements for their needs. Without adequate calcium, their new shell remains soft, making them highly susceptible to predation.
- Muda
- Regular
- When it is time to molt, the crab may temporarily leave its shell and hide within the live rock until its new exoskeleton is sufficiently hard. The shed exoskeleton strongly resembles a dead crab and is often mistaken as such by inexperienced aquarists. Ensure spare empty shells of various sizes are always available so they can upgrade safely post-molt.
- Reprodução
- Oviparous
- Reproduction in the home aquarium is an extremely rare occurrence and generally unsuccessful. They release microscopic, free-swimming larvae into the water column, which are usually swiftly consumed by corals and fish. Successfully raising these larvae requires dedicated pelagic feeding regimens and isolated rearing systems.
- Compatibilidade e companheiros de tanque
- Reef safe
- They are exceptionally peaceful toward fish and corals, making them an ideal and safe addition to any reef aquarium clean-up crew. However, they may occasionally squabble with other hermit crabs over desirable empty shells if resources are scarce. They generally ignore snails, provided there are enough empty shells to prevent them from killing snails for their homes.
