Critter ID on a hammer frag

[slik419]

Hey guys, new to reefing. I have a few hammers and a torch coral and the other day I noticed these pale/white things on my bicolor hammer frag. Hammer doesn’t seem bothered by it at the moment but pretty sure a few days ago I only saw one and now I see three. Can anyone ID this white thing? Not sure whether to just continue observing or if I should intervene?

Looks like a pineapple sponge on the top middle and bottom left a tunicate possibly

Pineapple sponge, harmless filter feeder,if bothering hammers extension,gently brush it off.
