Spawning Angelfish Help

[lomo]

Hi there, I currently have two angelfish in my tank, along with a few other fish (plec, loach, barb, mollie, etc)
Yesterday, I noticed the pair swimming around in one corner of the tank and found around 100 eggs laid on the back wall.

Several of the eggs have turned white, however I am not sure if the rest are fertilised or not.

Attached is a picture of the eggs, can anyone tell me what they think?

Thanks for your help.

congratulations, the white eggs are the bad infertile eggs by the way

Thank you yeah the male has been slowly picking them off over the last few hours. They are very protective over them. How long will it usually take for them to hatch? And how often do they spawn?

mine spawned about every 2 weeks or so..... the eggs will hatch but they will remain attached to the place they were laid by their heads for a few days then they become free swimming.
the parents may eat the eggs or fry until they get used to it or if the tank is shared then its guarenteed to happen by others if not the parents no matter how defensive they get im affraid.....
