Is my Molly Balloon fish pregnant?

[Jo.Leonard]

Hello. Is anyone able to identity if my balloon Molly fish is pregnant? The fish was purchased as a male but we have already had one set of babies so one of the fish is definitely a female, and this fish seems to be looking pregnant!

The black and the marble one are both female. The size of the belly differ per individual balloon molly specimen which makes it hard to tell wether one is pregnant or not. With balloon mollies, balloon guppis and balloon platies, it's best to look at the female from the top. Compare how much the abdomen has widened in comparison to males and non pregnant females.
