Good pictures. Nothing wrong with posting lots of pics as that's what we like!
I would says she's about to drop at any time but it is more difficult to tell with the balloon mollies. It seems you're pretty excited about the fry and rightly so if they're your first. I tend to just leave the mother in the main tank these days and let nature take it's course - survival of the fittest. I've had 5 baby platy's make it to adulthood from about 6 drops. When you're dying for them to give birth and keeping a close eye on the situation it never seems to happen. Leave them to it and you're forever spotting tiny fry swimming about.
I suppose what I'm saying is that with enough plants for cover some of the babies will survive. You could end up with a lot of mollies on your hands if you use the breeding traps.
By the way, the plant in the first pic with the red edges is a non-aquatic species
Good luck and keep us updated.
