Wow rhdoug,
That is a really nice established tank! I agree we dont see many bubble corals out there anymore, even though they are so cool...i see so many nice colors available out there...i have these three pieces up top and when lighting hits max, they get so big that block light from all corals below at times.
I hope my tank can get to the point yours is one day, with everything so vibrant and grown...that frogspawn colony is insane! When i think about a reef tank, that is what i picture, corals overgrown coexisting with others...nice!
