What Is This Thing Swimming Around After Vacuuming?

Hi I have an 8.5 gallon tank with snails shrimp and 5 fish. I did a siphon vacuuming of my gravel and there were all these little creatures swimming around in the water???! They were the size of maybe a sesame seed and were buzzing around at a pretty fast clip. They were really too small to identify anatomical features but they looked kind of oval with maybe a small row of legs underneath...kind of remining me a little bit of a horseshoe crab without the tail of course. Any idea what they could be? I tried to take a picture and video but they were too small for my camera to focus on. Thanks.

hi. have a look under tropical discussions for the "hitchhikers in freshwater tanks and ponds" maybe you'll find them in there.

Ah thank you. I believe they are Ostracods(Seed shrimp)!!

Thanks.
