Ecuadorian Hermit Crab

Looks how to spot one

exoskeleton

A small land hermit crab with a broad back and a soft, spiralled abdomen that it protects inside a borrowed shell. Its eyes are shaped like parentheses ( ). The body is covered in fine granules and the underside and inner legs are noticeably pale.5

Personality what they are like

Ecuadorian hermit crabs are highly active and curious, often exploring their enclosure day and night. They can be skittish around people and each crab has its own personality: some are bold and outgoing, others shy or even aggressive. They are best treated as a look-not-touch pet, as handling stresses them.345

Daily activity how busy a day looks

Very high activity level. They need plenty of climbing branches, hiding places, and deep substrate for tunnelling. They are quick and enjoy elaborate tunnels.54

Grooming and care the hands-on bits

Provide both dechlorinated fresh water and marine salt water in shallow pools with easy exits. Maintain high humidity (70-80%) and warm temperatures (24-27°C, or 80-90°F). Deep moist sand-and-coconut coir substrate is essential for burrowing and moulting. Always offer a range of spare shells, as they are picky about shell fit.45

Home where they are happiest

A warm, humid tank (24-27°C, 70-80% humidity) with deep moist sand-and-coir substrate for burrowing, two shallow water pools (fresh and salt), climbing branches, hides, and a range of spare shells. They are a coastal species and require access to seawater to maintain gill moisture; failure to provide it will lead to death.145

Food basics what goes in the bowl

Omnivorous scavenger. Feed a varied diet of commercial hermit-crab food, fresh fruit, leafy greens, vegetables, and small amounts of meat (e.g., insects, dried or freshly killed crickets). Always provide a cuttlebone for calcium. They can be picky eaters and may refuse food for days.345

Company who they like around

Very social animals that thrive in groups. In the wild they form large colonies and exchange shells. Keep them in groups; solitary crabs may become stressed. They are not suitable as handling pets and should be observed rather than touched.34

The story where it all began

The Ecuadorian hermit crab has been sold in the United States pet trade alongside the Caribbean hermit crab for many years. It is often marketed as a cheap, low-maintenance pet, but in reality it requires specialised care including access to seawater, high humidity, and a group environment. All pet trade individuals are wild-caught because they do not breed in captivity; they return to the ocean to reproduce. This makes the trade unsustainable.67
