Yep, I am going to make it a mixed reef like my 75G. I am also moving all my corals from my 40G to the 450G and putting my anemones in the 40 so I don't have to worry about them moving around and potentially nuking the big system.
The fish I have in there right now are the fish from my 75G; melanarus wrasse, diamond goby, purple fire fish, ocillaris pair, bangaii cardinals . Along with a few new fish I have added since starting it up; powder blue tang, naso tang, Adornatus fairy wrasse pair. Planning on adding a harem of anthias, clown tang, desardjini sailfin tang, blue hippo tang, copper band butterfly, pair of mandarins, blue dot jawfish, leopard wrasse. and maybe a few more
