Top picture has resplendents at the top, a Bartlett a bit lower down and a bimac female and male at the bottom. Second picture is my bimac 'super' male.
Bimacs are my favorite, though they need a big tank. Bartletts probably the easiest, though a bit aggressive. Resplendent are hard to keep in a mixed reef below about 2" in size as they just don't compete well for food.
