Yeah, it depends which way you are going. I'm going to start rebuilding the 240g I got (going to be FOWLR)... I plan on getting a Blue Face or Anularis Angel, a Blonde Naso Tang, an Eibli Mimic Tang, a pair of Blue Jaw Triggers a Harlequin Tusk and a few smaller fish...not sure what yet (Lawnmower Blenny, Flame Hawk) and I might keep the Singapore Angel that the tank came with.
There are lots of possibilities when you get up over 200g.
