Your thought's on re-stocking my 90g...

[TANGOMAN]

With the New Year came the loss of my buddy Lionell, the Volitan. I'm now operating a rather large aquarium for a lone Neon Damsel who has grown quite large and doesn't take kindly to new comers. He's going to be captured, one way or another, and relocated to the "basement-quarters".
Now comes the planning for a new group. I'm sitting on the fence regarding one fish and I think I already know the answer but I'd appreciate some thoughts. I've always wanted an Emperor Angel. With one of these guy's I lose the option of adding corals to this system though. Is a 90g too small to properly house one of these guy's ? I kinda' figure it might be...
I purchased beautiful pair of Clowns and a Yellow Tang from Incoma and they are livin' in the basement waiting for the Damsel to be evicted. I also purchased his Bi-color Blennie. He's quite a character as well. I had wanted to go with a Purple Tang in this system but yellow works for me ! A CBB is also on the list and I'm hoping to adopt a Valentini Puffer who need's a new home soon... .
So whaddaya' think, hold off on the Emperor ?

Those responses who display the greatest insight will be entered in a draw for a beautiful Neon Damsel. Large. Losing it's striking colors. Terribly aggressive and it destroys any coral presented to it. I may even offer a Seaclone as arunner-up prize...
