I just recorded this video of my glowlight tetras (Hemigrammus erythrozonus) spawning. You can clearly see how the female rotates and is turned upside down as the eggs are released. You can also see that the parents eat a lot of the eggs. The corys they share the tank with eat eggs too, so there will be no fry hatching in this tank. I have lots of glowlight tetra fry in a separate breeding tank, though.
