Hmm. Ive never seen that before. If by school, yo mean coexist, most tetras that are small love each other. if by school, you mean swim together, i dont think so. cardinals and neons are about the closest you get to different species schooling. hope this helps!
IME similar looking fish school together. For example my neons, black neons and glowlights all schooled together. I have also seen bleeding hearts, black phantoms, and bloodfins school together in a tank.
