The scavenger is a special kind of fish. They are called "garbage fish", and they have the function of cleaning the fish tank. Usually, they will stay at the bottom of the tank to feed, will be some of the garbage in the tank as their own food, such as some plankton, other fish feces and food residues at the bottom of the tank and so on. However, this does not mean that it can always eat garbage in the process of farming, and it also needs to be fed regularly when farming.
They don't need to be fed too often, just two or three times a week, and they can feed freely at the bottom of the tank at other times. Scavenger is an omnivorous fish, can eat a lot of food, but it is a slightly vegetarian fish. When feeding, you can mainly choose some plant feed, such as seaweed and aquatic plants. Animal feed can be fed less, such as blood worms.
The scavenger can eat a lot of food, it is an omnivorous fish, but they probably will not eat raw cucumber. The scavenger's mouth is sucker-shaped and usually sucks food into his stomach. They are toothless and there is no way to chew raw cucumbers. So, try not to choose cucumbers as their food. If cucumbers must be used, they can be cooked and eaten by scavengers after they soften.
