I think my Silver Molly fish is pregnant..?

Been there done that (; if you want to keep three then get a fry keeper ( your can get them for almost any pet store and also buy some fry food while your there , its cheap) and put the Molly in it when you see her having babies and when she has three of them let her out of the holder and let the three of the fry out when they get older and the other fish can't eat them , you know there old enough when there body is bigger than the other fishes mouths. It sounds mean but all the other fry will most likely become a treat for the older fish :S That's happened to me MANY times :P just use my advice (: Trust me it helps ((:
