I've Got A Feeder Guppy With A Gonopodium, And A Gravid Spot!

[justbinB]

I picked up a half dozen feeder guppies the other day, with the intention of starting my own population of disease free feeders. One of them I assumed was a female, with the characteristic bulging belly and gravid spot, but today I was feeding and noticed it has a gonopodium as well, and was moving it around as male guppies always do! It was being chased by the males like a regular female.

It is not fully grown yet, but the fish is certainly looking female with it's dull coloring and round belly.

Has anyone else seen this before?

Did it look like this?

this is a mule, both male and female, she even had fry but died before giving birth.
