[apples24]

the other female is untouched doing her own business at the top of tank were they all normally are

When mating, you'll see the male guppy pass beside the femaile and quickly rub against her as he goes by.
Those boy guppies are a super frisky breed!

Add one or 2 more females. The female being chased will be too tired out and stressed if this continues. A good ratio is 2 females to one male.

You won't be able to tell. They touch genitalia frequently, so it's not easy to tell when the insemination actually occurred.
