Can I Get Denison's Barbs?

[CCXGT]

I REALLY want some Denison's, and I was wondering of there might be any compatibility issues with my current fish.

So, in the tank so far:

2x Cherry Barb (2 Males)
2x Sunburst Platy (2 Males)
9x Neon Tetra (Unknown)
1x Red Swordtail (Male)
4x Guppy (4 Males)
1x Golden Gourami (Female)
10x Harlequin Rasbora (Unknown)

This lot get on absolutely fine right now despite the obvious crap most people and AqAdvisor keep telling me.

I was planning on 3 Torpedo's to fill in the Denison shaped hole in my tank.

All of those fish are pretty peaceful so it'd probably work. Also, tank size? Wouldn't recommend denisons in tanks shorter than 48 inches.

Sorry about the delay..

The tank is 160l (35 UK Gal), it is fully cycled but only about 2 months old.

There is no real plant life in there and I have 1 air stone.

I did do a bit of research on the Barbs and it's pretty clear that they aren't right for the tank.

Need an alternative now
