How To tell if damation molly is pregant

[jenanneph1978]

I am new to the Molly breed. I bought a dalmation molly and she is round in the stomach area but behind her rear fin by her anal there is a brown spot on her how can you tell if she is prgnant and how long do they carry before giving birth

If you have male she is pregnant. Gestation takes about 30 days. She will get very large and almost square looking when she is close to birthing.
