What hitchhiked on my LR?

So I'm slowly building a rockscape in a 29 gallon I set up last week. Tonite i added a few more pieces that apparently had some life in it. One rock has a few feather dusters on it, but then I also noticed alot of little white things floating around. They reminded me of shrimps but i know they arent. they are really tiny, I had to put on my glasses to see them. the power head keeps them flowing around the tank, i'd see one land on a rock or the sand, and then i'd see it move around.

What could they be?

Copepods or amphipods most likely

Okay good, thank you. i dont see as many of them, I think alot of them took a ride up the filter intake, but I did see a few crawling around on the sand and on the rocks
