What do y’all think about a datnoid or 2?

Datnoid should work if you don't want to just have SA species in the aquarium.

Keeping SA theme in mind, I'd add couple of large adult angels, some large geophagus species , maybe altifrons and a flagtail.

Would look cool.
Also try adding in some large rocks and driftwood to add in natural biotope feel
