Does this sound good?

If you can't adjust, Fishmonger, you can baffle it. :)

Flame gourami + cardinals sounds gorgeous! I can't wait to see pictures. :)

It has an adjustable flow direction so I can aim it at the wall or create a spray bar. The tank will be setup for a while so I don't need to worry about that, also I don't even have the tank lol. But I know for sure I will be getting it for free with the stand!

8 Cardinals? I will think about it, as I would like to have a big group, I guess that is still big though...

[Bombalurina]

I reckon you could squeeze as many as ten no problem. :)

once the tank is established and mature you can have a maximum of 12-13 as long as you keep up with water changes and keep them regular and stable

[kfryman]

Oh okay I will do that then, so at first I will just have like 7 or something, then after a while I will put some more in.

[Mo]

yup. Cardinals can be a bit sensitive at times but when the tank is established you can have your full group

Okay, so I am sure on getting tetras, either neons or cardinals, and a dwarf gourami.

Are there any fish like bettas and gouramis that are from South America or at least solitary fish that will fit a 16 gallon?

Gourami are from Asia. :p
Paradise fish is another anabantid, but they might be too aggressive for small tetra.
Most small fish school. Fish like anabantids are adapted to living alone due to the flooding/droughts and scarce resources that they have to fight over.
Nothing from south America comes to mind that is solitary and small.

I know gouramis come from Asia, I was just thinking that I could do a biotype. I guess it won't happen since South America is always having rain lol. Yeah I have heard of paradise fish being aggressive.

Don't do paradise fish. I had three and they killed each other. This is why I don't trust store workers anymore.
