Most all Corys breed the same.
Move your Corys to a separate breeder tank that had plants like Java Moss and Java Fern. Plump them up with live, meaty meals. Then before (I believe daybreak, although it could be sunset, doing this off memory), do a 25% water change with cooler than usual water. This replicates the rainy season rains that stimulate the Corys to breed.
After that it's pretty standard fry care
