Care Instructions:

• They prefer spacious, well-ventilated environments; glass tanks or reptile enclosures can be used for rearing.
• Substrate must be used; coconut fiber, bottom sand, and moss are recommended. Driftwood and hiding facilities (coconut bricks, bottom sand, moss, etc., available on websites) should be provided.
• They are good climbers, so the enclosure needs to be covered to prevent escape.
• It is recommended to prepare a separate molting bucket with thick coconut fiber for them to bury themselves.
• Insufficient humidity will lead to dry gills, so regular misting is required.
• Hermit crabs cannot drink tap water directly, which will lead to death. Purified water can be used.
• Both a freshwater bowl and a saltwater bowl must be provided simultaneously.
• Daily feeding can include fruits, fish and shrimp meat, or specialized crab food.
• When changing shells, you can provide them with shells that are 1-2cm longer than their old shell and have an opening 1-2cm wider than their old shell.
  

The shell opening diameter for hermit crabs with a shell length of about 1-2cm is approximately 0.8-1cm.

The shell opening diameter for hermit crabs with a shell length of about 2-3cm is approximately 1-1.5cm.

The shell opening diameter for hermit crabs with a shell length of about 3-4cm is approximately 1.5-2cm.

The shell opening diameter for hermit crabs with a shell length of about 4-5cm is approximately 2-3cm.

The shell opening diameter for hermit crabs with a shell length of about 5-6cm is approximately 3-4cm.

(Note: The color of Japanese Purple Land Hermit Crabs will change with the number of molts.)

Japanese Purple Land Hermit Crabs can range in color from light blue to deep purple, often violet-blue or reddish-purple. Juveniles have lighter body colors, becoming "blueberry" colored as they mature. We recommend using a sand and coconut fiber substrate for them to dig and molt. Always have extra shells available for the crabs to switch into.
