Hey guys

Sat down for a close look at my reef (4 months old) and noticed a few of these guys pulsing around the tank. They have 8 segments and they pulse like a jelly fish.
My first thought was a hydroid in its free swimming stage?
If so, is this something to be concerned about our just leave them be and let everything find its level?
