Like the Black mollies the Red Platy will not mate if the gh level is below 8.0! this I found out the hard way. waiting and waiting with the GH level being at 4.0. the week I changed this with the super gh booster which you can download here. Super GH

I have had lots of matings and fry, the average amount of fry per birth being 8. Again Being really careful of the GH level while doing the water change to keep that level at least to 8.0! and I keep the filer 20 percent dirty .
