just put them in a tank with some plants and they will do the rest. They scatter eggs in plants and a day or so later the eggs hatch. The fry are free swimming a few days later and can be fed on infusoria or fry foods for a week. Then newly hatched brineshrimp can be offered as well as the fry food.
The adults don't need any special requirements to breed, just good water quality and a well balanced diet. The fish will mature and breed when they feel like it.
