Benefits of fishing in the rain barrel
By keeping fish in your rain barrel, you won't just amaze visitors. Fish also drive away mosquito larvae, which often reside in the rain barrel. The insects only use calm waters to lay their eggs. In order to absorb oxygen, the larvae sit on the surface of the water, which supports them due to surface tension. But if fish bring movement into the water, the larvae cannot find any grip, fall down and drown. Some fish species even feed on microorganisms and thus prevent your rain barrel from being heavily soiled.
Care
Nevertheless, you still have to ensure that your rain barrel is permanently clean. However, under no circumstances should you use chemical agents for cleaning. This would have serious consequences for both the fish and the rest of the environment. You should also feed your fish. Choose light food, not sink food. Residues that settle on the bottom worsen the water quality in the long term.
