Most types of crabs live in the sea or offshore areas, and some live in fresh water or land. Can crabs feed themselves? Can.

If you want to raise crabs at home, you can choose to raise them in a pond if conditions permit. We need to put some aquatic plants in the pond, and because crabs are used for food, the water in the pond must be clean and hygienic. At the same time, clean and sanitary water is more conducive to the survival of crabs. Therefore, when building a pond, there needs to be enough sunlight and sufficient water sources. The height of the pond needs to be more than one meter to prevent crabs from running out. At the same time, the water in the pond should not be too deep. When raising crabs, there needs to be some mud in it, so as to better raise crabs.

If you don’t have a large space at home, you can use a large fish tank or deep container, preferably with a lid. Crabs live best in a humid environment of 18℃-25℃. So it needs to be placed in a ventilated and cool place. Add fine sand and stones to the bottom of the fish tank and plant some aquatic plants to create a good environment for crabs. Water quality: Freshwater crabs should be raised in fresh water, and sea crabs should be raised in seawater. It is best to change the water once a week and pay attention to keeping the water clean. Water temperature: needs to be kept above 15 degrees. Basking in the sun: You can let them bask in the sun, but not for a long time. Cleaning: Clean the crab's body and container regularly. Feed mainly egg yolks, small fish, shrimps, snails, etc. Feed 1-2 times a day, take them out in time if they are not finished. At the same time, crabs like to eat shellfish products, so you can sprinkle some small snails or clams (live) on the sand. Moreover, crabs are nocturnal feeders, so they need to be fed at night. In the morning, crabs like to get into the mud and rest.
