Will a non-prego guppie still have a gravid spot. If not, is there an average on the time period from when the gravid spot shows up to delivery?

Forgive the dumb questions. I've kept fish all my life (barbs, tetras, and Cichlids) but now my wife wants to try and raise fry so I'm new to the whole livebearer thing.

Guppies do not have gravid spot and don't develope a gravid spot. The only thing the female has is a black spot on the anal lining. It is really noticeable, and can even be seen on new born guppies. All you need to do is add a female, and a male. In about two months or a little less you will have guppy fry, But you will need a couple of things for the fry to hide in such as a lot of baby grass.

Well there is a spot that will appear to be a gravid spot. But If you look at the fry whether male or female, they all have that spot. As they get bigger, the male's spot fades away while the female's spot remains.
