Pregnant Mollies

We think our mollies might be pregnant, can anybody confirm this for us?
Sorry about pic quality.

Also, in the last day, one of the (maybe pregnant) mollies has become really aggressive to the other two mollies in the tank. Is this something to worry about? We can separate her if we have too.

Are they balloon mollies?

Well if they're female then theyre pretty much constantly pregnant

I don't think they're balloon mollies, they didn't look like that when we bought them.

The lyretail mollie is certainly pregnant, the 2nd one looks to be too, but certainly not so far gone.

The definite way to tell is whether they have been in the same tank as a male in the last 6 months.

If there is a male in the tank then they're nearly always pregnant.
They really are prolific breeders.
