I have a 55 gal. w/live rock (please see setup at: http://www.shopwithjean.com/Evzfishtank.htm ) I would like to add a dwarf angel as my Diva and last fish. It will have 7 happy companions. Anyone have comments/recommendations/suggestions? The Lemon Peel might be my first choice, but heard Flame is more hardy. What do you think?
