Identification help. Aiptasia ?

Saw this guy swimming in tank tonight.
He swam up from the bottom and attached to the glass. I’ve never seen an anemone swim before but it almost looked like a jellyfish.


while writing this post I saw two more and caught a video. It’s horrible quality but hopefully someone can help.

thanks,
Rob

Technically it is Medusa stage of Hydroid ,As hydroids have a sessile, polyp stage and free swimming stage of medusa.
