Females are able to store the sperm of a male for up to 6 months, so it is possible to have fry even with no male in the tank. Also most females that are bought is safe to assume that they are already pregnant, as long as their was a male in the tank where you bought them from. If you want to make sure that you have no fry at all than the best bet you have is to do males only in the tank.
I don't think my platys have reached full maturity yet, they're pretty small compared to full grown platys I have seen.
My tank is an 18.7 US Gallon tank. My planned stocked was 3 platies, 8-10 neon tetras, 5 pygmy corys and 5-6 pearl danios. My filter at max cycles 1200L an hour, however I've turned it down to half as my platies seemed to be struggling against the current.
