Halimeda and caulerpa

[ALH]

I have a rock growing what looks to be halimeda and caulerpa. I like the Halimeda, but should I be concernedabout the caulerpa taking over? I like the look of it so far, but don't want it to become a scourge on my aquatic landscape

Caulerpa does have the habit of taking over and when it does it's very hard to get rid off as it will return from even the smallest root.
I like them to and i would keep it if you like it but make sure its on an island away from any near by rocks, that way it will be easy to deal with.

It would have to be on a very far away island LOL. They stretch their roots out pretty far. Also, if you keep the caulerpa, trim it back often and a lot, otherwise it can go sexual and bomb your whole tank. I had that happen once before (that was my last tank crash before I took it down for 6 1/2 years).
