Perfect rock flower. I placed him right where I wanted and he made himself right at home. It's been 2 weeks and he seems like he's growing already. If you want a fast growing anemone, this one seems to be it.

They were much smaller than I hoped but they came healthy. I asked for three and I actually got four and they were all very beautiful and they’re doing well in my tank. I’m very happy with them.
