My black molly dropped 6 young about 4 hours ago and she still is kinda fat a little so how do I know when she is done giving birth? Also here is a pic of her yesterday!
. And here is a pic of her now! also here is the pic of her 6 young!
unfortunately I have no experience with mollies but I do breed swordtails.
I would leave her where she is for now she will need time to recover from the birth anyway but this will also give you chance to see if it's just swelling from the babies or if she is still holding some you should be able to tell by the morning.
When you feed her just keep an eye out if she is eating or not if not she is possibly still holding some, watch her though she may take the food into her mouth and then spit it back out.
when she dropped the baby are either hiding and you can't find them or were eaten. i would say about 24hr prior to dropping is when she will be 100% finished. let her recover with the lights off to reduce stressing and all will go back to normal.
