Scoly/sponge

[Davesreef’s]

I’m curious what’s growing under my scolymia. And if I should get rid of it or not worry

It is a pineapple sponge, harmless filter feeder

I’ve noticed it on a few of my coral/rock so wanted to make sure. Appreciate the feedback!

I second that, it’s harmless, sponges are something you want and they rarely bother corals unless its a fast growing one that can grow over corals which eventually smother them but its rare in my opinion to get that kind of growth
