Length of preggers...

...
Guppies are funny creatures, they can go on having fry for 6 months on one fertalisation.

. Also they tend to have a range of embryos in their belly all at different ages. Once that batch matures they are born, and the next lot move into place ready to mature. They can have fry ever 2 - 3 weeks like this until all fertilised eggs are grown on. My last young female had a batch of 12, the next day see looked quite big again and the gravid spot had grown. Now 2 weeks later shes square and ready to have the next lot

..how bonkers is that
So I would say keep an eye out and expect more babies in about 2 weeks
As for the others... guppies can delay the maturing of fry until they think the situation is safe to give birth. This way it seems they have been preggers forever

. A lot of people panic thinking the fish is going to explode

etc. So they move them and mess them about. This only serves to stress the fish further and delay the birth even more

. So the best thing to do is just leave them too it.
Turn up the temp to about 80/81 degrees, this will help the fry mature. If they do have problems, really there is not much you can do about it anyhow, and messing with a heavily preggers fish only causes more problems.
Good luck and let us know how many you get
