New 20 gallon tank

[oscarbuffalo]

I have a new 20 gallon freshwater tank. I have been researching fish and would like a tank with a pair of german rams and a twig catfish. What other fish would go well in this setup?

Some Cardinals? Get more than 2 GBR's. also, you'll be hard pressed to find females at your LFS (at least in my area) Usually they get added by accident - you have to gave a good eye.

(by "pair" I'm assuming you meant male/female pair)
