questions regarding my fishes about there sexes

Question
i was wondering can mollies change there sex? because i  two white mollies from the pet shop and they were both females and now one is a male and one is a femaale. well i hope you could let me know as soon as possible. thanks!

Answer
The simple answer is yes. If they were young and immature when you got them, they can "change" sex.  It's not really changing, it's maturing.  They all start out looking like females, then as they mature, the change takes place.

Hope this helps!!
