I have 2 dalmatian mollies, one of which is pregnant and she is being constantly harassed by my male...he just wants to mate constantly and that's been the case since I got them. It's been about 2 months now and the female is very very pregnant. I don't know the how long the gestation cycle is, or when she should be popping them out, but as of today the female just wants to hang out by the heater and the male is still constantly harassing her...pushing her around the tank at times. Yesterday I bought another female dalmatian to try and curb the problem...but I don't think my male really gets the point. I'm worried he's going to stress her to the point of killing her, and I'm fairly fond of the fish...is it time to separate her? I have a breeder cage but it is currently occupied in my girlfriends tank with a guppy that's squirting out babies. My mollie really seems weak...please help me!
