Definitely. They look like stubby bubble tips, but they arent long enough to really even flow in the current.

looks like a fuzzy mushroom or a riccordea to me
first rock i ever bought had some little white things that looked like those
turned out to be purple and green riccordea
also had a fuzzy mushroom rock fall and one was underneath the rock in the sand for a couple of months and thats almost exactly how it looked when it was getting colours back

I'm a risk taker, so I'd probably leave it for now and see what they grow into...

I agree with the mushroom comment. I have a bunch of fuzzy mushies and the little ones look like that.

its not a manajo a or a paly or a ric mabie some kinda shroom ?

Did I get anemone hitchhikers? Newb here
 

It's a paly 100%
