I really suggest you read into the things you are doing more before you take action. Next time, be sure you know what to feed, as many of the foods you feed fry need time to reproduce, and make sure you know exactly what needs to be done and at what times. Breeding is much harder than people put it out to be, and shouldn't be done unless you have a goal in mind. Breeding for the sake of breeding isn't such a great idea (not that I'm saying you're doing this).
It's just always best to know everything before hand, so you don't end up with your entire spawn failing. It's happened way too many times before, that I've seen, due to people not doing their research and thinking ahead.
As Indjo stated, 24-48 hours is the hatching period.
They should have infusoria in the tank (these are microbes that live on plants and in the water- so you will need live plants for this). The fry will eat that up until 2 weeks old. But you will also need to supply a high protein diet, such as microworms, bananaworms, vinegar eels, and baby brine shrimp. They cannot eat pellets, and rarely eat dry foods.
They should be in a 10-20 gallon with daily water changes at 2-3 weeks old. I wouldn't change the water until they are about a week old, and then start doing more and more heavier water changes.
