Some fish that would work great in a 20g
1. Cory cats
2. Harlequin rasbora
5. Neon or cardinal tetras
6. Just about any other tetra
I recently turned an empty 20g tank of mine into a planted betta tank. I'll be adding some neon tetras in a week or two.

I love how you tell people that fishless cycling can take forever yet you've never even tried it. My fishless cycle took a week and a half from start to finish how long do your fish in cycles last?
