How to keep a small crab alive?

1. You need to prepare a small environment suitable for the small crab to live in, which needs a water area, a dry area and a hiding area;

2. Crabs are mostly carnivorous, and you can feed them some fish, chicken, beef or mutton, but the leftovers must be cleaned up in time;

3. During rearing, you should also pay attention to temperature and hygiene; the temperature should not be too cold or too hot.

4. When rearing small crabs, you can separate males and females and not keep them together, as they will fight. Use a somewhat larger fish tank, and fill the water to a level higher than the stones that emerge above the water surface. Normally you can feed them a little salt-free raw meat; earthworms are also very good. Do not feed them steamed buns, as these will foul the water.

Among these, if the prepared crab shelter uses a sand-and-stone type substrate, a hiding place must be added, which can be purchased or made yourself. If you make it yourself, for larger crabs you can consider using half a flowerpot cut lengthwise as a hiding place; for small crabs, a beverage bottle cut crosswise is generally used as a hiding place.

To prevent escape, only when the distance from the highest point of the edge of the substrate in the container to the container opening exceeds 1.5 times the crab's leg span can the container be left open; otherwise, a lid must be added.
