looking for suggestions.

If it's taller than long, angelfish are good ones to get, but more Dojos are probably not a good idea. You might try smaller serpentine loaches. Kuhlis maybe? I'm not sure if those would be a good idea with angels, as they are quite small, even when full grown.
 
I believe dojos get fairly long, close to 10 inches I think and also prefer cooler water (lower 70's). That would leave barely enough room for them to turn around.

I would say a pair of angels, a large group, like 10-12, of larger-bodied tetras (lemon, diamond, bleeding heart, etc.) 10 corys and an Ancistrus.
