if you want fry, the easiest way to go about it would be to put some parents in a small breeding tank and then remove them once you see spawning behavior so the eggs are not eaten.
I have a tank of all egg layers (black skirts, danios, black neons). The danios spawn quite regularly in my java moss. I sold a friend some RCS and threw a chunk of java moss in the bag for the shrimp to cling to while he was transporting them and amazingly enough a few weeks later he had a baby danio swiming around in his *shrimp only* tank. I however have never once seen any fry of any sort..just too many predators in my community tank.
