Brown/Green growths on stems of corals?

[One Reefing Boi]

I’m not entirely sure how to describe it but it seems that a bunch of my corals LPS and Clove Polyps have these brown/green or white growths on them. They move in the current and kind of look like hydra? They have like 3-4 tentacles that come off them. I tried to get pics but will try again later for clearer ones

also lights just came on so that’s why they look sad and closed. Otherwise they all are open and eating and happy

On the zoas it looks like some kind of fungus maybe

They are actually clove polyps (lights just came on) and otherwise they are happy as a clam and open and responding to feeding reef roids when I do, just curios because their is a ton of them
