The water's pH level should be anywhere between 6 and 7.2. If we're talking about reproducing here, you're looking at 6.5 to 6.8 pH level. Make sure that ammonia level is not too high as this can cause your fish's mortality. Invest on a good quality filter to help you fulfill this task. What about temperature? The ideal range should be 76^oF to 80^oF.
