Just wondering on peoples experience with these things. I've had it about a month and seems to be doing good. Poylps are out during the day and quite a few trees on this rock.
Question I have is do they grow? Do they spread on the surrounding rocks?

I keep forgetting to add, be careful with shrimp in your tank, they will apparently pull the worms out and eat them!
