Anything that's too big to be eaten (which is just about any fish I can think of) and too peaceful to nip fins or give chase. Dwarf cichlids... you never know with any cichlids. A single keyhole cichlid or Bolivian ram would probably be fine, though. Dwarf pencilfish, smaller rasboras (emerald, harlequin, chili), smaller tetras (ember, green neon, ruby, cardinal), and cories should be fine. A 38 gallon is a good-sized tank, you could probably have a large school (10-15) of smaller fish in there.
