That's a sponge - as long as it doesn't start growing over and smothering the coral itself, it's a harmless filter feeder. Where it's growing now (around the base of the coral, rather than on the coral itself) isn't an issue, but you would want to keep an eye on it just because of how close it is to the coral. It most likely won't be an issue though.

Exposure to air usually kills sponges.Thanks. I think I'd prefer it off before it grows anymore, what's the best and safest way to remove these? Light toothbrushing in a separate bowl?
Good call. Its clatharina sponge which will overtake coral in time.Thanks. I think I'd prefer it off before it grows anymore, what's the best and safest way to remove these? Light toothbrushing in a separate bowl?
Probably the best suggestion for a situation like this would be to scrape it off and suction it out (I’ve heard suggestions to do both at once with a steel straw; that’s probably a good idea).Thanks.
