Growth on Star Polyps?

[Tullsterx]

Can anyone ID this growth on my star polyps? They're just waking up in the photo, and the growth doesn't seem to inhibit them opening up or anything. Bad?

Hard to tell from that photo, the top growth kinda looks like a pineapple sponge but the rest don't though.

Thanks. I'll try to get a better pick.

Yep, that's what are. And not bad, cool. Thanks.
