Generally, the adult black shell shrimp can grow to 2-3cm in length. There may be a small number of individuals who can grow to more than 3 cm, but basically can not grow to 4 cm. If the breeding environment is poor, they may not be able to grow to normal length. Their size is also related to their gender. Generally speaking, adult female black shell shrimp will be a little larger than male black shell shrimp.
Generally speaking, the black shell shrimp that grows to about 1.5 cm is sexually mature and can be reproduced. However, when culturing, it is more recommended to use shrimps with a length of more than 2 cm as the progeny of parent shrimps. Because the rigid mature shrimp is smaller and more difficult to reproduce. However, it is easier to breed shrimp with body length of more than 2 cm, and it is easier to breed high-quality shrimp seedlings.
The breeding frequency of the black shell shrimp is relatively high. When the water temperature is stabilized at about 26 C, they can reproduce basically every 30 days or so. After the female shrimps hatch eggs, the young shrimps can be hatched after 15-20 days. However, it should be noted that too frequent reproduction may affect the life span of parent shrimp. Therefore, when actually breeding, it is not recommended to let them breed too frequently.
