need help to ID

[JoaoMP]

These creatures appeared out of the blue a couple of days ago on my tank (2 months old). They move super fast.
Pictures are not the best but I hope you can ID them

4 weeks ago my trochus snails started reproducing. I dont think that is it but wanted to put it out there

Thanks!
