Strawberry Hermit Crab

Looks how to spot one

exoskeleton

The body and legs are covered by a hard, reddish-orange exoskeleton with white spots on the legs where hair follicles are. The eyestalks and antennae are also orange or red, and the eyes are steel grey or black and oval shaped. They carry a discarded gastropod shell on their back for protection.14

Personality what they are like

Strawberry hermit crabs are peaceful and social creatures that thrive in groups. They are active, especially at night, and enjoy climbing, burrowing and exploring. They can be easily stressed by poor conditions, too much handling or lack of hiding places. When threatened they retreat into their shell, and they may use their claws in mild disputes with tank mates.435

Daily activity how busy a day looks

They need plenty of climbing structures such as vines, plants and coconut huts, plus deep substrate for digging. They are most active at night and require a large tank (at least 30 gallons or 80 cm long for a small group) to accommodate their roaming and burrowing behaviour.425

Grooming and care the hands-on bits

Maintaining high humidity (80-85%) and stable temperature (22-29°C / 75-82°F) is essential. The substrate should be a moist sand-soil mix at least 8-10 cm deep to allow burrowing for moulting. A glass tank with a tight lid helps hold humidity. Daily misting or a fogger is recommended. Provide both fresh and saltwater bowls deep enough for full submersion, with exit ramps. Offer a variety of empty shells for swapping.425

Home where they are happiest

A glass terrarium of at least 30 gallons (120 litres) for a pair, or 80 cm length for a group of 3-5. Substrate: moist sand mixed with coco humus or forest bedding, 8-10 cm deep. Temperature: 22-29°C (75-82°F). Humidity: 80-85%. Provide both freshwater and saltwater bowls (deep enough to submerge), climbing branches, hiding spots, and a heat lamp or under-tank heater if needed. A tight lid is necessary to maintain humidity.425

Food basics what goes in the bowl

Omnivorous scavengers. In the wild they eat seaweed, dead fish, molluscs, invertebrates and young leaves. In captivity offer a varied diet: high-quality hermit crab pellets, fresh seafood (shrimp, fish, squid), meat (chicken, turkey, beef), fruits and vegetables (especially carrots, pumpkin, sweet potato for carotene), nuts, grains, seaweed, spirulina, and calcium sources like cuttlebone or crushed eggshell. Remove uneaten food promptly.425

Company who they like around

Strawberry hermit crabs are highly social and should be kept in groups of at least three to five individuals. Solitary keeping is not appropriate for this species. They can be housed with other land hermit crabs of similar size. Provide plenty of empty shells to avoid conflict. They are peaceful but may have mild pushing contests or feeler fights.435

The story where it all began

The strawberry hermit crab was first described in 1837 by French zoologist Henri Milne-Edwards from specimens collected in Mauritius. It has been known to science for nearly two centuries. Wild-caught individuals have been traded to aquarium hobbyists for many years, but they are considered difficult to keep because their natural habitat, the shoreline and treeline of tropical islands, is very hard to replicate in captivity. Even with ideal care, they rarely live more than a few years and never reproduce in captivity, so all pet specimens are taken from the wild.123
