yeah I hear ya. I was thinking about keeping the rock low - profile and letting some stags get huge in the back with an island near the front for bushier acros. I'm also adding two smaller tanks, a 29 g and a 20 g, for a softie & zoa display and a fuge. these were necessary as my friend is giving me two pairs of snowflake clowns. the nice thing about this is i can cover those two tanks and have a place for fish that like to jump.
For the main display i was thinking a pair of Genicanthus sp. angels, swissguard/swalesi bass or mystery wrasse, one of the less common pygmy angels or a sunburst anthias, and a few cool gobies. It's a tricky size tank to stock, not quite big enough for tangs or schooling anthias
