I bought some dalmation mollies 3 1/2 weeks ago. One of them was noticibly pregnant. After a week she seemed to be getting so huge so I put her in a breeding box for about 4 days. She didn't seem to mind being in there at all, but nothing happened. I decided to let her out and take my chances rather than stress her out. She is happy and eating well but getting bigger every day. My question is, How long are Mollies Pregnant? She was already obese when I got her, and it's been another 25 days. It looks like her belly is practicvally pushing into her gills. yet there is no gravid spot, or see-through area. Could she be sick and happy? Or are mollies pregnant for 2 months sometimes? What is up with this happy little fat girl??? Also, I set up a 10 gal fry tank using 100% vaccum water (and 1 cup of gravel) from the main tank, however the fry tank has a new filter. Can I still put the Molly in there to have her babies...if there are babies? I bought some stuff called "Cycle" but I'm hesitant to put it in there. Any help is appreciated.
