Whether it is necessary to raise scavenger in the fish tank, the breeder can make a decision according to his own situation. Because breeding scavengers has both advantages and disadvantages, the advantage is that scavengers have strong adaptability and can clean up moss and algae in fish tanks, so young scavengers do not need to feed food specially, and the breeding difficulty is relatively low. Keeping scavengers also has disadvantages, because they have the habit of sucking fish. If there are fish in the fish tank that are sick or in poor health, scavengers will harass them until the fish die, and they will eat the dead fish. Therefore, whether to raise scavengers in the fish tank depends on the choice of breeders and the variety of fish. If it is a fast fish, you can raise scavengers.

1. Feeding: Although scavengers can clean fish tanks, they will eat more when they are adults and prefer meat, so their breeders need to feed them when they are adults. But scavengers are always on the ground floor, so it is best for breeders to choose sinking feed to feed them.

2. Pay attention to sick fish: Scavengers have the habit of sucking fish. Breeders should pay attention to the condition of fish. If diseases are found, they should be isolated and treated as soon as possible to avoid scavengers chasing them for a long time.
