there is loads of info on here regarding breeding your cories. Many members have well documented their attempts, myself included, you'll just need to set aside lots of time for reading as there is a lot of it to read.
Peppered are supposed to be the easiest to breed but a word of warning - it's hard work
It's easy enough to get them breeding but finding eggs, hatching the eggs and then caring for the fry is no easy feat. A lot of us have tried and failed many times before finally getting the fry to survive.
Good luck with it and we'll look forward to reading your attempts
