When do I put a pregnant molly in her own tank?

Question

5 days ago I purchased 2 dalmation mollies, 1 male, 1 female. The female seems to be growing and looks pregnant. When should I put her in her own tank?

Answer 1

when she stops eating and starts to seem stressed is the best time doing so

especially when the male harasses here you should do it earlier

Answer 2

well you when you start to notice it doesn't eat. and for the tank of her own with tons of plants for the babies to hide or else the mom will eat them. If you just noticed it got bigger wait ten days just to make sure mine gave birth early and ate all of the babies
