Description de l'espèce
Geographical Origin and Habitat: Western Pacific: coasts of Japan, Taiwan, and the Philippines. Commonly found in tide pools, rocky shores, and shallow coral reefs at depths from 0 to 10 meters. This hermit crab inhabits the intertidal zone and rocky shores of the Western Pacific, tolerating significant environmental changes.
Taxonomy: Family Diogenidae, genus Clibanarius. Hermit crab with a soft abdomen protected by a gastropod shell, which it changes as it grows. Grows to 3.0 cm. Its morphology features robust walking legs adapted to rough terrain and equal-sized claws used to seal its shell opening.
Social Behavior: Peaceful and social scavenger. Spends its time crawling over rocks and sand searching for algae and organic detritus. Gregarious and highly active during the day, constantly crawling over the substrate in search of organic food particles.
Coloration and Sexual Dimorphism: Widely distributed in well-lit coastal rocky tide pools and shingle beaches. Sexes are indistinguishable externally; shell selection is based purely on size. The coloration ranges from olive green to dark brown, offering excellent camouflage among algae and coastal rocks.
Soins, reproduction et cohabitation
Tank Setup: Suitable for small tanks starting from 20.0 liters. Provide stable rockwork and keep a supply of empty shells of various sizes for growth. Requires an aquarium with stable live rock configurations and a constant supply of empty shells of various sizes for growth.
Diet and Feeding: Omnivorous scavenger. Constantly consumes nuisance algae, organic waste, and leftover fish food on the substrate. Omnivorous diet; feeds on hair algae, cyanobacteria, detritus, and readily accepts commercial sinking pellet foods.
Water Quality: Stable marine chemistry parameters: temperature 20.0-26.0 °C, pH 8.1-8.4, specific gravity 1.021-1.025. Sensitive to copper. Tolerates a wide range of water parameters, but prefers stable marine pH and specific gravity along with high oxygenation.
Compatibility and Tankmates: 100% reef-safe. Excellent member of the clean-up crew. May attack small live snails if empty shells are not provided. Peaceful and reef-safe; coexists well with small fish and other non-predatory invertebrates of similar size.
Aquarium Breeding: Releases microscopic zoea larvae into the water column; rearing them to settlement in aquariums is virtually impossible. The release of free-swimming planktonic larvae makes successful reproduction in home aquariums extremely difficult.
Risks and Diseases: Extremely sensitive to copper treatments. Lack of spare shells causes stress and aggression toward snails. Main risks include a lack of upgrade shells (which can lead to attacks on live snails) and extreme copper toxicity.

Profil d'invertébré
- Régime alimentaire
- Omnivore
- The diet of Clibanarius pacificus typically consists of organic detritus, microalgae, or specific planktonic particles. In a home aquarium, they constantly forage along the substrate or rockwork looking for nourishment. Supplemental feeding with specialized invertebrate pellets or liquid foods may be necessary. Ensuring a varied and nutritious diet will promote vibrant colors and long-term health. Overfeeding should be avoided to maintain optimal water quality.
- Rôle écologique
- Scavenger
- In the wild, Clibanarius pacificus plays a crucial role in maintaining the balance of its native ecosystem. They often act as natural cleaners, breaking down waste materials and unconsumed food. Their constant movement helps aerate the sand bed and prevent the buildup of toxic gases. By managing algae growth, they create space for slow-growing corals and sponges to thrive. A balanced aquarium ecosystem relies heavily on their diligent cleaning efforts.
- Taille adulte
- 3 cm
- Risque de saut
- Yes
- There is generally a very low jump risk associated with this aquatic invertebrate. They typically remain fully submerged and attached to the substrate, glass, or rockwork. However, some species may occasionally climb above the waterline if the tank is tightly sealed or if conditions degrade. It is still recommended to use a lid or screen to prevent other inhabitants from escaping. Maintaining high water quality will discourage any attempts to leave the aquatic environment.
- Sensibilité aux chocs
- Medium
- This invertebrate is highly sensitive to rapid fluctuations in water parameters. Sudden changes in temperature, salinity, or pH can cause severe osmotic shock and death. A slow and careful acclimation process, preferably drip acclimation, is absolutely necessary. Maintain stable aquarium conditions through regular monitoring and automated top-offs. Avoid performing excessively large water changes at once.
- Calcium et minéraux
- Medium
- Proper calcium levels are absolutely vital for the structural integrity and growth of this species. They continuously extract calcium carbonate from the water to build their shells, skeletons, or protective tubes. Maintaining calcium levels between 400 and 450 ppm ensures they remain healthy. It is also important to balance alkalinity and magnesium alongside calcium supplementation. Regular testing is required in heavily stocked reef aquariums.
- Mue
- Yes
- If applicable to its morphology, this invertebrate undergoes periodic molting to facilitate growth. During the molting process, the organism becomes extremely vulnerable to predation and stress. It is crucial to provide ample hiding spaces, such as caves or crevices, where they can retreat safely. Do not remove the discarded exoskeleton, as they often consume it to quickly replenish essential minerals. Disturbing them during this delicate phase can lead to fatal complications.
- Reproduction
- Oviparous
- Reproduction in the home aquarium is often challenging and rare for many invertebrate species. Most require highly specific environmental triggers, such as temperature shifts or lunar cycles. The resulting larvae usually have a prolonged planktonic stage, making them difficult to rear. Specialized food sources like phytoplankton are needed to sustain the offspring. Consequently, most specimens available in the hobby are wild-caught or professionally aquacultured.
- Compatibilité et compagnons
- Peaceful
- Compatibility varies largely based on the specific species and tank mates. They are generally peaceful but can fall prey to aggressive or predatory fish. Ensure they are housed with calm tank mates that will not nip or harass them. Research individual species requirements to avoid territorial disputes. Always monitor new additions carefully to ensure harmonious interactions.
