Water fleas?

You will want to go full screen to see these. These are swimming around in my macro tank. they look like little jelly fish, but move like water fleas. Marine water fleas or something else?

Do they look like this (Cladonema sp.)? Tiny glass jellyfish? We have lots of clinging hydromedusa in our setup at the moment.
Jellyfish warehouse has an article on common hitchhiker jellies

Sort of, but with only 4 legs. They don't attach to anything, just swim around. They are like little stubby rockets with 4 legs

Thanks. At first I was thrown off when googling hydroids then searched "hydroid jellyfish" and found something that resemles them. I think they got processed through the power head though. Bummer.
