2. Difference between shrimp claws: The big-eyed thief shrimp is more aggressive, and there are larger shrimp claws in the front of the body. And the male's pincers are bigger than the female's. The black shell shrimp is less aggressive, and the pincers at the front of the body are very small.
3. The difference of the eyes: The angle between the two eyes of the big eye thief shrimp is larger, almost 180 °. The angle between the two eyes of black shell shrimp is relatively small, ranging from 120 to 150 degrees.
4. The difference between the back: the back of the bigeye thief shrimp will bulge upward, while the back of the black shell shrimp will not bulge upward, which is relatively flat.

Bigeye thief shrimp and black shell shrimp can not be mixed culture. Because the bigeye thief shrimp is very aggressive, they will eat the black shell shrimp as a snack when they grow up. After a period of time, the number of black shell shrimp will decrease sharply. Therefore, the bigeye thief shrimp and the black shell shrimp can not be placed in the same tank when breeding.
