Caulerpa question

[fatpuffer]

I bought some rocks and it is covered with caulerpas. I like to keep a few like this since i am thinking of building a sump. But i would also like to put some in my main tank.

How can i get rid of the caulerpa in my rocks?any biological control for these? heard of foxface...any other?

These are grape caulerpas. They look great and wish i can keep them, but i do not want them going asexual in the main tank.


Thank you.
