Brown polyps spreading fast. They seem to like high light, and their surface is smooth not feathery. Is there any way to take care of these? Ty

Are they aiptasia?

 

[JCOLE]

Mix up a Kalk paste and squirt it on them. Do a little at a time and that should knock them back.

At first glance looked like big load off aiptasia,but after looking shape off the polyps ,looks like some kind of clove polyps so brown clove polyps.
How you get rid off them ,I've never had them to try sorry

But I also see tubes,so if you put your hand over or near them and they retract into a tube then could be feather dusters I guess

Doesn't appear to be aptasia. Mojanos?

 

[ACIAMPA]

No I’m familiar with aiptasia it’s doesn’t look like that. These have long arms like runners and use those to spread

Some kind of clove. You may have to get in there and scrape them. Can the rock come out? Better off outside the tank.
