Crusty stuff growing between polyps

[robwcormack]

Just noticed this stuff. Not sure what it is. Had a bumble bee snail on it for a few minutes that I pulled off. Any ideas? Sorry my phone doesn’t take great pics of stuff in my tank so this is about the best I can get. Any suggestions on taking better pics is welcome as well. I’m pretty new to this stuff still. Thanks

Sort of looks like colonial tunicates

Is that bad and urgent to remove? Just put the frag in there about 2 weeks ago and I did super glue it to the piece of rubble it’s on. Honestly kinda wondered if it’s just some crusty super glue that got on there while either gluing them to the rubble or the rubble to the rock.

They're safe, filter feeders
