The bigeye thief shrimp will eat the black shell shrimp. Big-eyed thief shrimp has a pair of large shrimp claws, which are very aggressive, while black-shelled shrimp have no defensive ability, so they may be preyed on by Big-eyed thief shrimp. If these two kinds of shrimps are kept in the same tank, if they are not fed for a long time, they will be very hungry, or when the black shell shrimp is in the shell period, the defense ability is very weak, the big eye shrimp is likely to prey on the black shell shrimp.
The big eye thief shrimp's prawn claws give it a strong aggression. In addition to eating some shrimp, it can also eat small fish. Especially the newly born small fish, they can easily prey on them. For some smaller fish, even adult fish can hunt. Therefore, it is not recommended to breed them in the same tank with small fish in practice.
The bigeye thief shrimp has a very mixed diet, and even aquatic plants can be eaten. But when there is plenty of algae or other food in the tank, they generally do not eat aquatic plants. They usually only eat tender shoots, but sometimes they dig out the roots of aquatic plants. Therefore, they can not be placed in a grass tank with shallow roots of aquatic plants, otherwise the aquatic plants can not grow normally and will soon be destroyed by them.
