Angelfish Eggs

My Angelfish have just laid eggs on a amazon sword left!! The question
is what shall I do now. I want to leave the eggs in there but maxamise
the chance of hatching. I have read several things on the internet

darkness reduces fungus
angelfish and other fish might eat the eggs at night so i would leave
a 'night light' for them
higher temps mean it will hatch faster....

So this is what i plan on doing...turning them temp up by 1-2 degrees
for now. Set up a dimmer light for the eggs tonight and hope for the
best. Anything else I can do to help?

Also the male is VERY torn up..he has lost 30% of his scales is there
anything I can do for him?
