Some kind of bug on top of my plants

I did not notice before, but now it seems like I have some kind of bugs on
top of the leves of my floting plant, the same kind is on the glass of the
aquarium. It seems like it is not going down into the water, just on top of
the water. They are abouth 1mm yellow/red or smaller, difficult to see them
wery clear. when I tried to squeese them they just jump away. They can
"walk" on the water.

Someone got anny qlue what it is, how I can get rid of them ?
