In my experience when you find a single baby and the mother has stopped birthing usually the fry have been eaten. I got to witness an entire birthing process beginning to end this last round, the whole process lasted around 15 minutes, I was over the tank catching babies as they dropped, still lost at least two to hungry mouths, the mother herself went for one.
I would wait at least a month before reintroducing the fry.
