About Hermit Crabs：- Hermit crabs have a soft, delicate abdomen and in order to keep it protected they wear shells on their backs.\r\n- These shells are not a physical part of the crab, rather they are borrowed from other shellfish. As the crab grows, it will need to move into bigger and bigger shells. Some crabs just love to change shells for fun, or to find a better fit.\r\n- Always have a broad selection of different sizes as some hermit crabs like to wear shells that seem too large or too small for them.\r\nPlease note:- New shells should be sterilized in boiling dechlorinated water for five minutes and allowed to cool before being given to your crabs.\r\n- Please never use painted or glazed shells for your pets,as they are dangerous and potentially toxic to hermits.\r\n- We choose only premium shells, but these are products of nature and occasionally may contain a small cracks, chips or other imperfections, please make sure you do not mind before you bid. Thanks for your understanding.\r\n- Small parts, not suitable for children under 3 years old.
