Invasive Prown coral taking over

[fragger69]

I've recently gotten this bloom of these brown wavy corals. They are growing over everything and I don't want them to end up taking over the tank. Need help with ID and removal please.

Please post pictures taken under white lights.

I cant tell from the pictures. But if its only on one rock at the moment. Remove the rock not matter what it takes to get to it. Then you can remove the corals etc from that rock that you want to keep and then kill the corals you want to remove by say burshing it and then covering with kalk paste.

Sorry, I didn't even think about the white lights. There isnt anyway of me taking the rocks out, so that isn't really an option.

Yellow polyps. Research proper removal of these. I’m sure someone has a thread on it.

Tidal Gardens - Parazoanthus Coral Care

Yellow Polyps are are a close relative of Zoanthus and Palythoa from the Genus Parazoanthus. There are several species of Parazoanthus in the wild, but the most commonly seen species in the reef aquarium hobby are the bright yellow Parazoanthus gracilis.

Possibly colonial hydroids

It also looks like you may have several “pest” anemones in the mix there (bottom right corner of the second pic, they form a line heading into the yellow there, and they seem to become more yellow the farther into the mass of yellow they get; first pic they’re above the orangish-brown mass in the center and they trail up to the right, going above the snail).

Also, the brown polyps in the bottom left of the first pic are different than the other brownish polyps (they have branching/feathering on the tentacles).
