It would work with just one female though, and if you kept 7 cardinals it would be a lil under stocked and if you kept 9 it would be packed. I'd keep plants ofc.
I would not have other fish in with cardinals in a 20g, aside from suitable substrate fish and in this case corys and/or whiptail catfish or Twig Catfish. A group of 9-12 Paracheirodon axelrodi and the catfish, that's it. Though a group of pygmy hatchetfish on top would not hurt. But no cichlids; just my view. I have had many species of "dwarf" cichlids and they always find characins annoying, to varying degrees. And in small spaces this kind of stress is significant.
