parrot fish spawning

[ado]

i've been searchin the web and have noticed that most sites state that successful breeding of BP is very rare and almost impossible, but still some have been able to do it. my question is: My two BP laid eggs about 24hrs ago and i see very few white "infertile" eggs what are the chances the eggs will hatch and what should i be doin to improve the likelihood of this happening? should i seperate the eggs and parents from the main tank? thank you in advance
