Caulerpa nummularia - what to do with it?

[tgurske]

Looks like I have "Caulerpa nummularia." While I think it's neat, it is starting to block the light from some other things. I let it grow from a single stalk but if it's something that I will end up regretting later, maybe I want to start eliminating it. Thoughts?

If you like it, prune it back. Pull out any runners that are heading for corals. If whatever is fueling it continues, it'll all grow back but many times caulerpas just run out of something necessary and die themselves.

If you prune it, send it to me. I use different Caulerpa species in my fuge
