Guppy: He or she

[FrozenFins]

I picked up from the store a month ago, what i thought was two male guppies. Now one is really fat, and only gets fatter. I haven't fed him/ her in a few days in hopes he would loose some fat, instead hed gaining fat.

Now I think its pregnant, but its a male isn't it? Or am I wrong and its a female?

If it is more colourful and has a gonopodium its a male

Sure looks like a male

See Pictures:
Female guppies have a triangle anal fin.

Male guppies have a stick-shaped anal fin called a gonopodium to help transfer sperm to the female when mating.

Looking at the pictures, I can't tell 100%. I have seen females with long dorsal fins before. The anal fin isn't exactly captured there. I think a picture with a side view would be better.

Since fish are always moving, you could set your phone camera to video, record a clip, and then screenshot a clear frame as you scroll through the video manually.

after looking at the pictures I think its a male. But that just doesn't explain why it gets fatter every day without me feeding it. I will send a pic as soon as the tank lights turn on.
