What are these?

Do they have a name? They came on my rock and grow like crazy.. Thinking of getting rid of them since they're all on one rock.its the polyp in the middle.

Ugly brown palys. I have ugly blue palys. I squirted them with aptasia x yesterday and it seams to be killing them. Squirt each individual polyps mouth

Thanks.. I might try that.!

Is it possible that these could change color? I've had my AI nano on my tank for about a week and they're starting to get some green in the center.

I took a pic this morning.

yep you might have had bad lighting before the AI and now they are coloring up

I've seen the brown ones turn green. But they're still ugly, and spread like a disease

They are kinda gnarly and do spread fast, kinda cool though.
