Do a bit of reading on bubble nest builders...that will answer all your questions.
Basically the male will start off by building a bubble nest either at the top of the tank or under leaves which are at the top of the tank!!
He will then coax the female over with his manly moves and treat her to a bit of a "get your eggs in there or I'll beat you" ritual.
When the eggs are released and fertilised the
male will scoop them up in his mouth
nasty I know!!...and he will then put the eggs into his bubble nest.
At this stage your best seperating the female from the male (leaving the male in the tank with the bubble nest (the womans job is done!!)) The male will guard the eggs like there's no tomorrow and will hassle, chase and even kill anything that comes near them.
Once they are hatched I think you should remove the male at this stage (not sure on that point) because he may eat them!!
