When they turn solid white they definitely aren't fertilized.
Otherwise, all I can tell you to do is wait.

Usually it takes something like 24-36 hours for them to hatch into wigglers, then another few days to a week and they should be free swimming. If its a tank with fish, most probably wont make it even that far though.

Void has the right idea, just wait it out and try again if needed, once the egg scatterers start breeding they wont stop unless something changes.

Eggs will also die if not kept in the dark. No tank lights can be on. This is just one of the numerous reasons people don't breed them due to the difficulity.

my neon tetra eggs are swaying back and forth but they are still a round shape is this normal?

Very hard to raise neons, the tank needs to be more or less in darkness for the eggs to stay viable. Then have to watch out for the adults eating them.

Is there anyone else who has bred neon tetras successfuly

I got given 3 tetras, I've got a 3ft tank and ATM I've got 3 male swordtails and a female guppy who is currently pregnant, I took the neons out of my 3ft tank and put them into a smaller tank while my guppy was having babies, I've recently found eggs in my 3ft tank, attached to the fake plants, I found 2 groups of eggs, 2days ago I found them, and this morning I seen one group of eggs wriggling, the other group I think is more exposed to light, they havnt changed but they're clear looking, but the other group of eggs who were in the dark corner of the tank have disappeared as of this afternoon, I'm thinking they might have hatched and sitting in the gravel... I understand it'll take a few days for them to start swimming, but will I be able to see them before then? Is it possible my snails Or my swordtails could eat the newly hatched tetras?
I still can't believe I found eggs in my tank, was not expecting babies from the tetras
