Ahhh, not particularly sure what species they are but they commonly referred to as Medusa hydroids in this hobby. They move in a jerking jellyfish like motion right? They are quite common in younger tanks (below a year) and they should normally disappear on their own in a matter of weeks of months. As far as I know, they don’t cause any harm to corals, inverts or fish.
