Hello everyone, this is my first post

I've just started keeping mollies. I bought 2 males and 3 females, reasoning that having more females than males would be a good idea.

They were pretty small when I bought them, but having kept platies I was totally confident that the shop assistant had sexed them correctly when I took a look at the anal fins.

However, I've been on holiday for a week and come back to find what appears to be 4 males chasing 1 female around! At the moment I'm debating whether she'd be more or less stressed if I set up the back-up tank and removed her.

My question is: are mollies fish that change sex as they get older? Were they just immature and too small to sex properly? If they have changed sex, is it to do with the tank conditions in some way? Will they change back, or is it going to be a case of taking some of them back to be exchanged?

I'd appreciate any advice on this one.

I heard of fish that do change.... but can't remember what type or the name. I never heard of Mollies changing but I don't know everything. IMO it was just a case of wrong sexing at the LFS. I gather that you want baby mollies. So I would sperate the female is she already preg. and after she has the fry take back a few males. you will shorty have more Mollies than you will klnow what to do with. I have one male mollies with 5 female Mollies and right now I have a tank full of mollies, but I have an outlet for them so its all good

how long have you had them? do you have any nice colorful males?

sometimes, males will look like females in the wild type. they also tend to be smaller..... how big are the mollies in question?

Hi, had some trouble logging in but thanks for the replies.

The mollies in question are standard black non-sailfin mollies.

Small, about 3/4 inch perhaps?

they were juveniles.... it's likely that they were too young to tell if they were male or female.....
