South american 10g

Betta/Paradise fish/dwarf gourami
6 pygmy or panda cories

couple pair of Shell dwelling cichlids

6 small tetras/white cloud minnows/rasboras/danios

8 guppies

pair of honey gouramis
6 pygmy cories
 
Shell dwelling cichlids are very small african cichlids that likes to make their homes in large shells. There are a couple of different shell dwellers, all are very territorial around their shell. Correction, only 1 pair for a 10 gallon tank.
 
My suggestions for a 10 gallon SA tank:

4 pgmy cories
6 cardinal or neon tetras

Not too much choice I guess since it's a 10 gallon, but those two species are from SA and pretty small yet interesting.
