There's a ton of nano fish out there. For your tank though, I'd suggest a school of 8 of ONE of the following:
Microdevario kubotai OR nanus
Boraras brigittae (or any Boraras species in general)
Hyphessobrycon amandae (the ember tetra)
Nannostomus marginatus (dwarf pencilfish)
Micronemacheilus cruciatus (zebra hovering loach)

The boraras come from a similar environment as the pygmy's do (stagnant water, warm, acidic)

@Fishbeard, is this the same tank as mentioned in your previous thread(posted below)?
