    I think my dalmation molly is pregnant, but I'm not positive. I managed to snag a picture, thought maybe someone can help? The link is below. I do have a breeder box, but I know it's stressful to move them too soon. If she is pregnant, what should I watch for, or is there really no way to tell in advance? Thanks SO much!

    So... let's say you move her in the breeder box. What are you going to do with 2 dozen new mollies? And the next batch? And the next?

    I'd like to save the first batch. I do have two tanks so room is not an issue. I do realize that with mollies and guppies in my tank, eventually for population control, I will have to leave them and it becomes "survival of the fittest." I only have two dalmations -- bought them that way in case they were to breed, but I would like more. Thanks.

    A heavily gravid female livebearer will bulge outwards towards the rear of her abdominal cavity and get a black spot around her vent. For a large livebearer like the Molly it is really difficult to achieve a transfer stress- free, due to the large size of the female Molly versus the (relatively) small size of the breeding net. When a livebearer gives birth the fry aren't going to be targeted immediately. In many cases, there only is going to be mild interest or maybe the adult livebearers are just going to ignore them. You could let the female birth naturally and then catch all the young fry and then transfer those to the breeding net where food competition will be less intense.

    + 1 to madagascar, I don't know how many friends have lost Mollies to stress by moving them to breeder box's.

    From looking at the picture you are safe in assuming that your molly is in fact pregnant. I agree with madagascariensis and steeler. Those breeding boxes are small. Since you mentioned having multiple tanks, another option you might consider is isolating the mother in a fully cycled tank of her own where the newborn fry will have plenty of hiding places. That way you could avoid the stress of the breeding box. Things to look for in her behavior will be isolation from other members of the tank such as hiding in small areas, and in some rare cases territorial aggressiveness.
