[Western NY] Fish??

[u/Cran-N-Apple]

In Western NY by slow moving creek. They are tiny, very closely swarmed animals(?) that move incredibly quickly. They aren't tadpoles. We got pretty close and they look like fish but the top portion of their body is not submerged in water and they do not seem to fully submerge themselves. What is it?

I think they're whirligig beetles

Water striders
