Black shell shrimp can eat fish eggs, but generally do not do so. Because the eggs are usually guarded and cared for by male or female fish to help hatch. If the black shell shrimp goes to eat, it is likely to be gnawed or eaten by the parent fish. They will not provoke the fish when they have enough food, and they are lucky if the fish do not attack them.
Black shell shrimp and fish can be raised together, but not 100% to ensure safety. Because almost all fish have the habit of eating shrimp. As long as they are big enough, they will eat the shrimp. Therefore, in order to mix black shell shrimp and fish, we must find some small fish mixed culture. They should not be mixed with large fish, or they will be easily eaten. In mixed culture, attention should be paid to the establishment of avoidance, you can plant some aquatic plants, put some shells, so that shrimp can avoid the attack of fish.
Black-shell shrimp cannot be raised with larger adult turtles, or they will be eaten. They can be raised together with young turtles, and when the size difference is not large, they will not attack shrimp when the turtles are fed. When the turtles grow up, they should be fished out of the shrimp tank in time to avoid eating the black shell shrimp.
