Platy fish, female or male??

[Natasha93]

Hi, I’m wondering if anyone can tell me what sex my three fish are. There constantly chasing/fighting each other. And I’m worried the red one might actually be pregnant as it looks bloated .

Thanks in advance!

The way to tell the difference is by the anal fin; that's the one underneath the body right in front of the tail. If it the usual fan shape, the fish is a female but if it's more of a rod shape it's a male.

Looking at your photos I can't see the anal fin clearly enough, but other members who keep these fish will be able to tell you better. But even if you have all females, it is possible for them to be pregnant as they can store sperm and use it to fertilise eggs for many months. So if they've been in a tank with males at any time during the last year, they could be pregnant.

Some better photos from the side would help some more. It's a bit hard to tell from the angle these photos are made.
