Do Fish don't eat leeches. Leeches are still very harmful to fish. They can adsorb on the surface of fish, absorb its blood, and even cause its death. Usually can not use leeches as feed to feed fish, you can choose live baits such as water fleas, blood worms to feed, but must ensure sterility, preferably after disinfection, or thawing after freezing, otherwise it is easy to cause fish disease.
if there are leeches in the fish tank? 1. Manual removal: If there are leeches in the fish tank, it is best to remove them at the first time. It should be noted that this animal's reaction speed is very fast, and there are serrations on its mouthparts, which can be bitten by it if you are not careful, so it is better to wear rubber gloves so that it is safer to remove them.
2. Add salt properly: The simplest way to clean up leeches is to add salt. Because of the osmotic pressure, leeches that can survive in fresh water will lose water continuously after entering the salt water environment, which will lead to their death. This way can not only destroy adult leeches, but also destroy the eggs.
3. Biological management: Although leeches are harmful to most fish, there are still some fish that can kill them. For example, cichlid fish is an expert in killing leeches. Therefore, you can raise some six rooms, pearl tigers and so on in the tank. These fish will soon eat them up.
