This stuff is like a weed in my tank. I've been giving away slices for the past month and the nubs on the rock I cut it off of grow back in a week. I have enough for 3 or 4 ppl right now. I'm at 30th and 1st in Manhattan most evenings.
They are very cool but like already said, grow like weeds. I had them in my tank and finally decided it was enough and got rid of them all. They were growing everywhere and over everything. Even my most aggressive corals had no effect keeping them in check. I gave some to my LFS, went back a month later and they told me they couldn't sell them fast enough, haha. Became a big problem for them :division:
