If you could do it again what would you do

Well I think Ive decided on a 30L x 30W x 18 H tank,

My only concern is the lighting. Im thinking acro dominated,

What set up would be your recomendations? I am going to suspend the fixture from the ceiling, no retrofits.

Is a pendant with a 400HQI enough? I am concerned about the tank having a spot light effect, and that the corners will be fairly dark?
