Hermit crabs cannot be kept in fresh water. Hermit crabs are arthropods and seawater crabs. They cannot be raised in fresh water, and the osmotic pressure in fresh water is small, which is not conducive to the growth of hermit crabs. To raise crabs, first prepare a fish tank, spread a layer of fine sand at the bottom of the tank, and then put two pots in the fish tank, which are filled with fresh water and salt water respectively. Usually you can choose corn, fish and shrimp to feed hermit crabs.

Can hermit crabs be kept in fresh water? Hermit crabs are arthropods that live in snail shells. The maximum diameter of snails can reach15cm or more. Hermit crabs live in the Yellow Sea and southern waters, and cannot be raised in fresh water. The osmotic pressure in fresh water is small, which is not conducive to the growth of hermit crabs.

Morphological Characteristics of Hermit Crab The shape of Hermit Crab is between shrimp and crab, with long body, asymmetrical body, soft and long abdomen, which can be coiled in a snail shell and powerful claws. When crawling, it uses the third and fourth steps to support the snail shell.

How to breed hermit crabs? Prepare a fish tank. Lay a layer of fine sand on the bottom of the tank. The sand is 3-5 times higher than the hermit crab, which can make the hermit crab hide and shed its shell. Then put two pots in the fish tank, filled with fresh water and salt water respectively, to balance the salinity of water in the snail shell. Usually you can choose rice, eggs, corn, small fish and shrimp to feed hermit crabs.
