Wrinkled Land Hermit Crab ( Coenobita rugosus )

• They prefer spacious, well-ventilated environments; glass tanks or reptile enclosures can be used for rearing.
• Substrate must be used. We recommend coconut soil, bottom sand, and moss. Driftwood and hiding places (coconut bricks, bottom sand, moss, etc. available online) should be provided.
• They are skilled climbers, so the enclosure needs to be covered to prevent escape.
• It is recommended to prepare a separate molting bucket with a thick layer of coconut soil for them to burrow into.
• Insufficient humidity will lead to dry gills, so regular spraying is required.
• Hermit crabs cannot drink tap water directly, as it will cause death. Purified water can be used.
• Both a freshwater bowl and a saltwater bowl must be provided.
• Daily, you can feed them some fruits, fish and shrimp meat, or specialized crab food.
• When they are changing shells, you can provide them with shells that are 1-2cm longer and 1-2cm wider at the opening than their old shell.

Hermit crab size is based on the opening size of the shell:

Hermit crabs with a shell length of about 1-2cm have a shell opening diameter of about 0.8-1cm.

Hermit crabs with a shell length of about 2-3cm have a shell opening diameter of about 1-1.5cm.

Hermit crabs with a shell length of about 3-4cm have a shell opening diameter of about 1.5-2cm.

Hermit crabs with a shell length of about 4-5cm have a shell opening diameter of about 2-3cm.

Hermit crabs with a shell length of about 5-6cm have a shell opening diameter of about 3-4cm.

(Note: The color of grayish-white hermit crabs will change with the number of molts.)
