I've got rocks buried with each of them, and i already dose the tank with my coral, so i'm good there. I'm in the process of relocating some lps under ledges, my elegance was cringing in the open on the sanded, after that i can ramp the lights up a bit higher, but that maxima has been ok down there for the past year now. I think Gigas will be the one species i won't own, but i'm pretty sure i have two more species left to go.
