Many people have probably heard a saying that burying scavenger fish alive is the best way to deal with it. This is done for a number of reasons. First of all, this fish has no food value and low ornamental value, they can be used to clean fish tanks. It is better to dispose of them properly after they are not raised. They should not be placed in other waters while being disposed of.
Because they are omnivorous fish and have no natural enemies, it is easy for them to reproduce rapidly and destroy the ecological balance in the water if they are put into the water. Moreover, they will feed on some fish eggs in the water, which will affect the survival of other fish in the long run, leading to their decline. Moreover, although they can clean up some garbage in the water, they produce more garbage themselves, which may pollute the surrounding environment in the long run. So, burying them alive is a quick way to get rid of them, and it's not harmful.
As mentioned above, when dealing with the scavenger fish, burying them alive is the best choice. If they are released in rivers, streams or other waters, they will have no natural enemies. In addition, their own vitality is also very tenacious, they will reproduce rapidly, the number will easily exceed the limit, destroy the balance. They also eat the eggs of other fish, and the amount they eat is very large, which is easy to endanger other fish. Moreover, the garbage they produce may also pollute the waters. Therefore, releasing animals is not a wise choice.
