Generally, it is not recommended to raise golden snails and fish together. Because the golden snail can eat small fish, and some big fish may eat the golden snail. So it is difficult for golden snails and fish to coexist in a fish tank. Although golden snails mainly eat dead and sick fish and generally can not catch healthy fish, they will also eat healthy small fish in a small probability. Therefore, it is not recommended to breed golden snails and fish in the same tank.
Gold snail and goldfish are not suitable for breeding in the same tank. Because the golden snail is likely to attack goldfish, especially small goldfish and young fish, it may become the target of attack. Therefore, it is more recommended to separate fish and snails. In addition, the golden snail will also eat aquatic plants. If there are water plants in the goldfish tank, they will also destroy the water plants. So it is not suitable for raising with goldfish.
Golden snails can be raised with shrimps, but not with large crayfish. Because large crayfish are very aggressive, they may eat golden snails. Although they may eat shrimp, but because they are very slow, basically can not catch up with shrimp in the water, so mixed with shrimp is basically no problem.
