How fast do molly fry grow?

Given the correct contitions and heaps of room and food, Mollies grow quickly. The smaller types of Black and Spangled Molly will be mature enough to breed at 3 months and about 1-2"long. The larger Midnight and Sailfin Mollies, although capable of breeding earlier should be grown on for around 10-12 months until they are around 4" long.
