Thanks Laurie. I was told it was a Clavularia " Clove Polyp" when I bought it. When I was setting it up a small piece broke off. I put it on the right side, its growing good.
Yes it is a very interesting hobby. I have had fresh water for over 30 yrs, but can see this could be even more addicting. I have a 180g I'm building a stand and hood for right now. Hope to start setting that up in 3 or 4 weeks.
I also want to set up a 24 AP with sps.
