I’ve started noticing this under some of my corals. Anyone know what it is? ef5a8de79ebace922eb78fc2bdacd3f6.jpg

I think it looks more like a sponge. I have the same thing in several of my tanks. Harmless, I think they’re sponges. They feel like my pineapple sponges do

Is it raised from the skeleton or pretty flat? Looks flat to me, (could just be the angle) thats why i leaned towards coralline.
