do not put tinfoil barbs in there for the love of god.
I had 12 redtail tinfoils in my 225, with a 5x3 footprint and they used every single inch of that space.
I have a 4x2x2 (120g) in my room and I wouldn't dream of putting tinfoils in there, mine were all 8-10".
in my 120 I just have white skirt tetras, they were so cheap and they have a nice round shape that makes them hard to eat. They are also extremely easy to keep. Columbian tetras work equally well.
Congos too, because they get pretty hefty and add some nice color to the mix, I got 5 of them and lucked out to get 3 males and 2 females, lots of color!
