The hairy crab does not recognize its owner. Because its IQ is very low, it can be said that it has no IQ, and hairy crabs are cold-blooded animals. Therefore, in addition to recognizing food, it is still more difficult for it to recognize its owner.

Although hairy crabs do not recognize their owners, long-term feeding can form a certain reflex, so that they will not resist feeding people and will not show fear. After raising a hairy crab for a long time, although it does not resist the owner, it will not become dependent on the owner.

How to raise hairy crabs:

1. To raise crabs, use a glass tank as a container, cover the bottom with fine sand and stones, and then fill the tank with river water. Or lake water.

2. Crabs are omnivores. If possible, they can be fed red worms and egg yolks. Of course, crabs can also eat the offal of chickens and ducks or small fish and shrimps.

3. When cultivating crabs, you should pay attention to the appropriate amount of light. The embryo needs to be in a dark environment at all times in the early stage of development, while later development requires a certain amount of light. Insufficient light can easily lead to poor development of larvae, affecting molting and survival rates.
