I thought I would do this so the good folks of this forum don't have to repeat themselves all the time.
Nano tanks are capable of housing fish but most of what your LFS will sell you is not suitable.
I will try and compile a list of nano fish that can be kept in nano tanks. Any which I miss or you do not think should be in the group they are in, tell me and I'll modify the list. This list will also not include shrimp because I have no idea what sized tank is suitable for what specie.
> 12L or 3 gal
Betta Splendens (Betta or Siamese Fighting Fish)
> 20L or 5 gal
Dario Dario (Scarlet Badis)
Trichopsis Pumila (Sparkling Gourami)
Poecilia Wingei (Endler's Guppy or Endler's Livebearer)
Poecilia Reticulata (Guppy)
Carinotetraodon Travancoricus (Dwarf Freshwater Puffer)
> 28L or 7 gal
Boraras Brigattae (Mosquito Rasbora or Chili Rasbora)
Danio Margaritatus (Celestial Pearl Danio)
Hyphessobrycon Amandae (Ember Tetra)
Microdevario Kubotai (Green Neon Rasbora)
Aplocheilichthys Normani (Norman's Lampeye)
Microrasbora Erithromicron (Emerald Dwarf Rasbora)
