Most fish eat shrimp, few fish are pure herbivores, even grass carp can eat some insects, and shrimp itself lives under the water and will inevitably be caught by fish, especially when it changes its shell, it will be attacked and eaten by fish before the new shell becomes hard. For some fish, shrimp is not only a delicacy, but also can help them change color and make their body surface look better.

1. Choose the right variety: You must choose the right variety for mixed culture of fish and shrimp. When the fish is big, it will eat shrimp, and when the shrimp is big, it will hurt the fish. Usually, small tropical fish such as lamp fish should be selected for fish. Because they live in the upper and middle layers of water and are very lively, they will not be scared, while black-shell shrimp can be selected for shrimp.

2. Provide shelter: Because shrimp needs to change its shell every once in a while, the new shell will be soft at first, which will inevitably be attacked by fish at this time, and it is very fragile, so it is best to provide a shelter so that it can hide and ensure its own safety.

3. Pay attention to isolation: If the fish raised are relatively large, it is best to isolate them if they are mixed, and the water body can be separated from top to bottom with an isolation net, so that the fish can't reach the lower layer and will naturally not hurt the shrimp. In addition, it is best to ensure that there is enough space in the fish tank, which can also reduce the possibility of conflict.
