Striped Hermit Crab
Clibanarius signatus
The Striped Hermit Crab is a small, hardy algae grazer from the Red Sea. Peaceful and active, it makes a superb clean-up crew member for reef aquariums, requiring varied empty shells.

Description de l'espèce
Geographical Origin and Habitat: Native to the Red Sea, Gulf of Oman, and western Indo-Pacific waters. It resides in intertidal habitats including rocky shores, mangrove zones, and shallow tidal pools, sheltering in empty snail shells.
Taxonomy: Member of the Diogenidae family, genus Clibanarius. Described by Heller in 1861. It is closely related to other small reef-safe hermit crabs but distinguished by its unique leg pattern and high salinity tolerance.
Social Behavior: Peaceful and active. They spend their time crawling over rocks, sifting sand, and cleaning algae. They are social but will argue over empty shells if there is a shortage of larger housing options in the tank.
Coloration and Sexual Dimorphism: Features thin dark longitudinal stripes on its greenish-brown legs, with pale spots. The claws are subequal and covered in small bumps. No visible external sexual dimorphism is present.
Soins, reproduction et cohabitation
Tank Setup: Suitable for reef tanks and nano setups starting from 40 liters (approx. 10 gallons). Provide a mix of sandy substrate and live rock. Scatter plenty of empty shells of various shapes and sizes to prevent shell fighting.
Diet and Feeding: Omnivorous scavenger. Excellent at eating hair algae, film algae, detritus, and fish waste. If the tank is clean, supplement their diet with spirulina pellets, seaweed sheets, and tiny pieces of frozen seafood.
Water Quality: Keep standard reef parameters: temperature 23-27°C (73-81°F), pH 8.1-8.4, specific gravity 1.021-1.025. Ensure adequate calcium and magnesium, and dose iodine regularly to support successful molting cycles.
Compatibility and Tankmates: Reef-safe and compatible with peaceful fish and corals. Provide extra shells to prevent them from targeting live snails (such as Astrea) for their shells. Avoid keeping with large triggerfish or puffers.
Aquarium Breeding: Breeding in captivity is very difficult. Females carry eggs under their abdomen. Hached larvae are planktonic and require specialized rearing tanks with live micro-foods, which is rarely successful in home aquariums.
Risks and Diseases: Extremely sensitive to copper-based treatments and elevated nitrate levels. A lack of iodine will lead to molting failures. They can be preyed upon by aggressive crabs or large bottom-dwelling fish if unprotected.

Profil d'invertébré
- Régime alimentaire
- Herbivore
- As a diligent scavenger, Clibanarius signatus spends its days foraging across rockwork and sandbeds. Its diet is largely composed of detritus, uneaten meaty foods, and nuisance algae. Providing sinking pellets can ensure they receive enough nutrition when natural food is scarce.
- Rôle écologique
- Scavenger
- Hermit crabs like Clibanarius signatus play a vital role as part of the benthic cleanup crew. They tirelessly consume decaying matter, helping to prevent the buildup of toxic ammonia and nitrites. By constantly shifting the substrate, they also promote beneficial oxygen exchange.
- Taille adulte
- 3 cm
- Risque de saut
- Yes
- Clibanarius signatus relies entirely on its shell and the substrate for protection and does not jump. However, they are excellent climbers and can scale silicone seams, equipment cords, or rock structures. A secure lid helps ensure they do not accidentally venture out of the tank.
- Sensibilité aux chocs
- Low
- Clibanarius signatus requires stable water conditions to thrive over the long term. Rapid changes in specific gravity or temperature can induce significant stress. Drip acclimation is recommended over at least an hour before addition to the main display.
- Calcium et minéraux
- High
- Proper calcium and alkalinity levels are critical for Clibanarius signatus to sustain a healthy exoskeleton. Furthermore, they depend entirely on finding abandoned calcareous shells for housing. Providing an assortment of slightly larger empty shells is mandatory for their continued growth.
- Mue
- Regular
- When it is time to molt, Clibanarius signatus will often bury itself in the sand to protect its highly vulnerable state. It will shed its old exoskeleton and remain hidden until the new one is adequately hardened. Do not disturb a molting crab, as it can easily suffer fatal damage.
- Reproduction
- Oviparous
- Captive reproduction of Clibanarius signatus is extremely rare due to its complex planktonic larval stages. Females will brood eggs underneath their bodies until they are ready to be released into the water column. The larvae require highly specialized foods and stable marine conditions to survive.
- Compatibilité et compagnons
- Peaceful
- Clibanarius signatus is a peaceful scavenger but may fight with other hermit crabs over desirable shells. It should not be trusted around sluggish snails, as it may kill them to steal their housing. Keep with appropriately sized fish that will not harass or eat small crustaceans.
