blue crayfish is blue magic shrimp, which eats fresh and tender grass roots, humus, aquatic plankton and artificial compound feed.

Methods of raising blue crayfish:

1. The size of the fish tank should be determined according to the number and volume of shrimps. Four adult shrimps can be raised in a one-meter fish tank;

2. The bottom sand should be black masonry, coral sand and volcanic rocks, and the ratio is one to one.

3. The PH value of water should be controlled between 7, 2 and 8, because acidic water quality is not conducive to the growth of shrimp molting, and it will also form soft shells, which will bring harm to the normal life of shrimp;

4. Just control the water temperature between 1 and 32 degrees Celsius.
