Stocking question

[LCieParagon]

So I have a blackwater tank with a pH of around a 5.8. It's 48 gallons and heavily planted with tons of driftwood and java moss. I have in it 3 male bettas, 2 blue rams, 6 neons, and 6 cardinal tetras. I over filter like crazy: I have a canister for a 60 gallon tank + Fluval C3 both filtered with peat with de-ionized water during water changes and a powerhead. Tank looks nice. How would adding an altum angel sound? I'm definitely going to add a nanochromis transvestitus once one becomes available to me. I don't want to overstock it but I want a good amount of fish. I want a little challenge.
