Yup, and they have a root like structure on the bottom of that rock that goes into the sand. It just started growing this past week, so I'm not sure if it has released spores yet. I best get on it before it spreads.

The difficulty is that my flowerpot grows out of this rock and is very finicky about being touched. I don't know how well it would take to a dip, besides I don't think a dip would get all the rhizomes. Maybe an injection of lemon juice or vinegar?

Hi:

I have something that looks similar in both my Nano's. I was warned at the LFS about putting this in my tank. It suits want I want but it could grow out of control.

By the way I just picked up a purple flower pot coral. How do you find keeping yours? Light, flow and placement in your tank.

Thanks,
Michael
