1. Is it necessary to keep a scavenger in the fish tank There is no need to keep a scavenger in the fish tank. As a tool fish, the scavenger's main function is to clean up the residual bait. As for feces, he won't eat it. Moreover, this kind of fish eats more and excretes more, so it can improve the water environment in a short time, but it will lead to deterioration of water quality after a long time. In order to improve the water environment, besides changing water, it is necessary to strengthen filtration, and at the same time, it is best to control the feeding amount.
2. What fish are scavengers suitable for raising with1. Tropical fish: Scavengers are tropical fish, so it is best for breeders to mix them with tropical fish, so as to avoid discomfort caused by different breeding environments. If you keep it with cold water fish, one of them will always feel uncomfortable, so they can't keep it in good condition.
2. Fish with faster swimming speed: Scavengers have the habit of sucking fish. In polyculture, breeders need to choose some fish with faster swimming speed. For example, guppy, rat fish, mermaid with eyebrows, doghead fish, traffic light fish and so on. A fish that is too slow may not escape its attack.
3. Cyprinidae or lipid cyprinidae fish: Small scavengers can choose to be raised together with cyprinidae or lipid cyprinidae fish, such as rose fish, white cloud golden silk fish, zebrafish, tiger skin fish, etc. Because they are not big, they will not interfere with each other.
