Jumping animals on the water surface / Springtails (Collembola)

Some tiny animals have been living on the floating plant leaves and the water surface for about 6 months. They are brown and jump like fleas. What could this be, and do I have to do anything about it?


these for sure are springtails (Collembola).

They are very common (for instance, they can also frequently be found in flowerpots) and entirely harmless. They even serve as live food for some fish that live close to the surface.
There is no reason to combat them.
