Harmful to Fish: Scavenger fish are better at eating moss when they are young, but as adults, they will no longer eat moss and will develop the habit of sucking fish. In addition, adult scavengers also like to eat fish eggs, and some scavengers that have been without food for too long will eat small fish. Harm to the environment: Scavengers are an invasive species and have no natural enemies in the wild in China. If they are released into the wild, they will damage the local ecosystem.

I. Harmfulness of scavenger fish 1. Harmful to fish: scavengers will eat the moss and algae in the fish tank when they are young, and they will also eat some of the food left by the fish. But after they become adults, they will be more partial to meat and will have the habit of sucking fish. If there are other fish in the tank that are injured, they will keep sucking the mucus from the other fish until the fish dies. After the fish die, the scavengers will quickly eat their bodies. In addition, scavengers like to eat fish eggs. When very hungry, it will also eat smaller sized fish.

2, the harm to the environment: scavenger fish belong to foreign invasive species, they are adaptable and harmful to the environment, coupled with the fact that they have no natural enemies in our country, if accidentally released into the wild, will seriously damage the local ecological environment.

Two, scavengers do not want to raise how to do scavengers do not want to raise if you can choose to give away, you can also ask the local aquarium whether to recover. Generally the aquarium will recycle the fish. If you can't give them away, you can kill them.

It should be noted that scavengers can't be released because they have no natural enemies in the wild in our country, and if they are released into the wild, they compete with the local fish for food, and they will also eat the eggs of other fish. And their reproduction is relatively large, if left alone, the local fish will likely disappear.
