Ditto the concept that the biggest fish for this small footprint will be something not much larger than about 2".
Relatively sedentary would help.
Mated pair of almost any soft water dwarf size of cichlids:
Kribs (there are several species, might have to order from a breeder), Rams, Anomolochromus thomasi, Apistos (several species)
then a small school of some upper level fish, perhaps match the water system the Cichlids came from, definitely a smaller fish, so you can get enough to make a proper school.
Dwarf Rasboras, smallest Tetras or how about some of the smaller Killies that stay so high up?
Alternate pattern: Show fish at the top, lower swimming school:
Pick one: Betta, Honey Gourami
Pick one species, about a half a dozen fish:
Almost any small Rasbora, Tetra, Barb.
Pick one species, half a dozen:
Any of the Dwarf Cories (C. habrosus, pygmaeus etc.) or their close relatives, Aspidoras
Couple of Otos
