I have an established 58G RR tank with a 20G sump. Currently have various lps, sps, softies, 2 clams, and 2 small clowns. MY lfs has a small yellow tang about 1.5 inches. My wife really wants him. I like the tang but want him more for the reason that this is the first interest that my wife has shown in the tank. It may help me get her over from the dark side! Thoughts?
