Cory eggs what to do?

hi im after your advice please. Just noticed peppered cory eggs in my dads tank. (didnt intend on breeding as bought 3 peppers and one albino from same tank in fish shop when very small some many months ago and its turned out there is at least a male and female that have bred) so i have removed the eggs from the side of the tank and placed them in a plastic breeding box thing that suckers to the inside of the tank so they dont get eaten but what else should we do to try and keep and hatch them? advice please many thanks
