1, first of all, you can use a larger basin or fish tank to raise ornamental crabs at home. Usually, fish tanks are used to raise them. Put some colored stones and soft sand at the bottom of the jar, and pour the sun-dried tap water into the fish tank, so that the water will not damage the crab shell. And some aquatic plants, such as algae and aquatic plants, can be planted in the fish tank to create a good oxygen supply environment for watching crabs.

2. Secondly, the feeding of ornamental crabs, because ornamental crabs are omnivorous animals, can feed chicken egg yolk, animal viscera, fish and shrimp, Chinese cabbage, dried soybeans, pumpkin foam, potatoes, snail meat, red worms, etc., and are not picky about food at all, so they are very good to feed. Feed it twice or three times a day.

3. Finally, the carrying ornamental crabs should be cleaned frequently. When cleaning, hold the crab by hand, and then clean it with a toothbrush dipped in soap, especially in deep gaps. Pull its feet to brush. Then, rinse with clean water. Fish tanks also need to be thoroughly cleaned and occasionally sprinkled with salt to prevent diseases.

4. In addition, the aquarium for raising ornamental crabs must not be filled with oil, otherwise the ornamental crabs will be damaged due to the water quality, and don't eat too much, which will also affect the water quality.
