The black shell shrimp is a kind of freshwater shrimp, so it can be kept in a freshwater tank, but not in a seawater tank. Because they can not adapt to the high salinity of the water environment, they can not survive in the sea. Don't add salt to the water when you breed it. Or they may grow poorly. If the salinity is high, they will probably die.
Black shell shrimp can produce brown algae. In addition to brown algae, they can also remove Ulothrix. Because they can feed on algae, they have the ability to remove algae. Keep them in a tank with algae, and they can survive without feeding. If you want them to remove algae, don't feed them shrimp food. In case they get used to eating shrimp and never eat algae again.
Black-shell shrimp are mild and small, so they do not threaten fish. It can be kept in the same tank with some small tropical fish, but not with aggressive fish or large fish, or they may be eaten. When mixed with fish, it is recommended to place some shrimp houses and plant some aquatic plants to provide shelter for them so as not to be eaten by fish.
