Is My Gully Pregnant

[Bethhy]

I have recently brought two female guppies and they both have a black spot on under their tails, one of these spots are bigger than the other!
Help I don't want them to loose the babies or eat them so I need to know if they are so I can put them in a separate tank!
Please help

Welcome to the forum Bethhy.
I have a link in my signature area to a thread where I describe the stages of a molly as it moves from one fry drop to the next. I never pay any attention to the colored area called a gravid spot because most of my fish show no such sign. Actually, one of the few that do show a gravid spot is guppies and I use my usual method with them as well. A link in my signature area called My Molly's Progress will take you to that thread. The thread is heavy with pictures and commentary about what I saw at each stage of development.
