1. Abdomen difference: After adulthood, the abdomen of male and female black shell shrimp has a more obvious difference. The abdomen of the male shrimp is relatively slender and relatively small, while the abdomen of the female shrimp is obviously larger. The difference between male and female shrimps can be clearly seen by comparing them together.
2. With or without ovaries: After adulthood, observe the rear of the head of the female shrimp, and the ovaries can be directly seen. It is more obvious when viewed against the light. The male shrimp has no ovaries, even if placed under the light source, the ovaries can not be observed.
3. Habit difference: During the breeding period, the male shrimp is more active than the female shrimp. If a shrimp is found to be chasing other shrimps, it has a high probability of being a male shrimp.
4. Body size difference: In most cases, the adult female shrimp is larger than the adult male shrimp. However, this is a general rule, which is recommended as a basis for auxiliary judgment. Because there may be a few cases where this rule is violated.
Male and female black shell shrimp can be placed in a fish tank inside the breeding. Because this kind of shrimp temperament is very gentle, there is no cannibalism habit. When they are raised together, they can live in peace as long as the breeding environment is adjusted. In addition, keeping them together is not only convenient for management, but also good for their reproduction.
