The gray-white hermit crab does not recognize its owner. Hermit crabs have no IQ, only instincts. They are emotionless creatures and will not interact emotionally with humans. If the owner puts the hermit crab on his hand, the hermit crab will pinch the owner's hand because it feels nervous and stressed.

Notes on raising hermit crabs:

1. Hermit crabs have very low requirements for equipment. They can be raised in glass tanks, storage boxes or washbasins. You can put some rocks or wood in the breeding tank as shelter. In daily life, hermit crabs need fresh water and salt water. The salt water should be mixed with sea salt as much as possible.

2. Hermit crabs are omnivorous animals. You can feed them fruits, vegetables, bread, small fish and shrimps, etc. once a day or two.

3. Hermit crabs are saprophytic animals. If the environment is too dirty, bacteria and parasites will breed, which will cause the hermit crabs to become sick. Therefore, the owner must do a good job in environmental sanitation management and remove food residues and feces in a timely manner. Clean up.
