You're already overstocked.
I'd keep the 6 severum only (you're gonna have to move a few of them at some point) and add a few schools of different kinds of tetra/barbs/loaches to give the tank a lot of movement and color.... like 10 adult serpae tetra, 10 adult odessa barb and a school of yoyo loaches. The severum would be the centerpiece obviously.
