Algae ID please?

[Raeloni]

I'm trying to figure out if I need to worry about this. It just popped up and seems to be spreading fast. At first I thought it was tiny mushrooms. The leaves are about the size of a pea. It is fairly high in my tank and I have t-5's. There are vines that are sprouting out and starting to spread to other rocks. I was looking though the ID's and the closest thing I can come to is C. Nummularia. Any extra info if that is what it is would be wonderful! Thanks in advance!

Caulerpa racemosa

I believe you are correct in Caulerpa nummularia.

Should I get rid of it?

100% yes, it is extremely invasive. While there's still not much of it is the time to get it out. To make sure you remove the whole thing, you need to get all the roots out where they attach to the rocks.

I have one little rock in my frag tank with this stuff on it, and it drowned out the zoas on it's rock. The runner is very fragile, it'll probably take a couple tries to get rid of it.
