? Generally, the medaka will not eat the adult black shell shrimp, because the adult black shell shrimp is similar to the medaka, so the medaka can not eat the black shell shrimp. Secondly, the shell and head of the black shell shrimp are relatively hard, and the medaka can not eat them. Finally, black-shelled shrimps have claws. If they are attacked very fiercely, their claws will protect themselves, so the medaka can't eat adult black-shelled shrimps in general. But if it is the eggs of black shell shrimp or the black shell shrimp that is molting, it is possible to be eaten by the medaka. Because young black-shell shrimps are small and have no ability to resist, and when molting, black-shell shrimps have no ability to defend themselves and can only be attacked by people, so young black-shell shrimps may be eaten by medaka.
? Medaka and black shell shrimps can be polycultured. Medaka generally move in the upper layer, while black shell shrimps are in the lower layer. Generally, they will not meet each other, so they are suitable for polyculture together. Moreover, the requirements of water temperature and water quality for medaka and black shell shrimp are similar, and black shell shrimp can remove most algae in the fish tank and help keep the water clean.
However, when the medaka and the black shell shrimp are mixed, the breeder needs to plant aquatic plants or place a shelter in the fish tank, so that the black shell shrimp can have a place to hide when molting.
