Descrição da espécie
Geographical Origin and Habitat: Indo-West Pacific, including coastal areas of Australia and neighboring islands. It primarily inhabits intertidal zones, rocky tide pools, sheltered shorelines, and shallow reef flats where it crawls among macroalgae and rubble.
Taxonomy: Belongs to the family Diogenidae, genus Clibanarius. Grows to an average size of 3 to 4 cm. Features an asymmetrical soft abdomen that it protects inside empty gastropod shells, and equal-sized claws designed for feeding and climbing.
Social Behavior: Peaceful, active, and social scavenger. It spends its time searching for detritus and algae. It is highly gregarious, showing little intraspecific aggression as long as there is an abundance of food and empty shells.
Coloration and Sexual Dimorphism: Usually displays olive-green to brownish body coloration, with robust legs and thick, long, distinctively colored antennae (hence 'antennatus'). There is no visible sexual dimorphism, with genders appearing identical externally.
Cuidado, criação e companheiros de tanque
Tank Setup: Well-suited for marine community tanks and nano reefs of at least 30 liters (approx. 8 gallons). Provide plenty of live rock for climbing and a selection of empty sea snail shells of various sizes on the substrate for growth.
Diet and Feeding: Omnivorous and detritivorous. Feeds on detritus, film algae, hair algae, and leftover food. Sinking algae wafers and pellet foods can be offered if the tank is very clean, ensuring they receive enough food.
Water Quality: Maintain standard marine parameters: temperature 22-27°C (72-80°F), pH 8.1-8.4, and specific gravity 1.021-1.025. Copper-free water is mandatory. Regular iodine supplementation is beneficial to support successful molting cycles.
Compatibility and Tankmates: Reef-safe. Compatible with peaceful fish and other reef-safe invertebrates. Avoid predatory fish (e.g., puffers or hawkfish). Provide empty shells to prevent them from targeting live snails for their shells.
Aquarium Breeding: Breeding in home aquariums is not documented. Fertilized eggs are carried by the female inside her shell. The larvae are released as plankton and are extremely difficult to raise, as they easily succumb to filtration systems.
Risks and Diseases: Primary risk is shell fighting if empty shells are scarce. They are highly sensitive to sudden changes in water salinity and temperature. Ensure a slow drip-acclimation process of at least 45 minutes before adding them.

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
- 3.5 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
- Medium
- 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
- Periodic
- 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.
