Is my male guppy actually a female?

[Crthomas87]

Hi Everyone

I’m completely new to the aquarium scene and after setting up my tank and doing a lot of research I decided I would start with a 20 gallon tank of 8 male guppies (I don’t want any babies showing up). I went to the store 3 days ago and picked them out. However, I’m starting to wonder if one of them is female? I would feel terrible if there was one female for 7dudes. I haven’t noticed any aggressive behavior by the other fish but the more I look at this guppy the more concerned I get. I’ve attached two pictures. Any experts want to weigh in on this? Thanks!

looks like a female. If you can, get a close look at the analfins on her underbelly. You'll notice males have modified ones that look "crumpled" whereas the females have the more traditional looking fish fins.

Looks female to me

Do you know what type of guppies they are?

+1 vote for female. Fins, body shape and colouration all look female to me.

I can't quite tell from the pic. Sometimes you get one that is kind of inconclusive till full grown. I'd say there's a chance it's a male who's gonopodium is forming late. I had a late bloomer like that whose colouring was more like a female too.

Thanks for the advice all! I’m going to bring her or him back to the store and see what they say. The fins look different to that of my other fish so I’m pretty sure I’ve got a female.

It looks like one that's a late bloomer. I had a male like that. He had no interest in mating or chasing around the females. Unfortunately he passed a year later.
I've also had males with gay tendencies. It would chase and try to mate with another male. This mostly happens with younger, inexperienced fish. But eventually they get it right.
