I just purchased 6 mollies from petland (2 male 4 female) and 2 of the females look sort of plump but notnot too plump, kind of like a large belly. Do you think that they are pregnant? What are sure signs of pregnancy? If they are how long do you think it would be before I should expect to see fry. Also if they are pregnant how do i know when to place them in the breeder.

Ok, so you know that ur molly is pregnant if it has a bulging underside, kinda like she swallowed a marble. now that she’s pregnant, you need another tank with about 5-10 gallons in it, if you know it’s TIME, you will put her in a breeding net. i’m sur they can be bought at petsmart or something. when the eggs are born, they will be put in a special spot, which is probably somewhere on the net. if you need further info check this page: http://images.google.com/imgres?imgurl=http://gallery.pethobbyist.com/data/16077MaleWhitesailfin.JPG&imgrefurl=http://news.pethobbyist.com/index.cgi/archive/fishtales/20030627000000/&h=595&w=699&sz=44&hl=en&start=4&um=1&tbnid=ZXo4Vxj_pXLhoM:&tbnh=118&tbnw=139&prev=/images%3Fq%3Dpregnant%2Bfish%26um%3D1%26hl%3Den%26rls%3DTSHA,TSHA:2005-45,TSHA:en%26sa%3DN
P.S. look for the plump molly pic
it is very simple to tell when mollies are pregnant near the gender fin of females it looks big and when they are ready to be put in a breeder the big part near there gender fin goes blackish. with black mollies you can’t tell whenn to stick them in a breeder just when they have been pregnant for 4-6 weeks.
