Sexing platys

[Kengel]

Hey, how do you determine the sex of platys? I've heard something about black spots on a female, I thought I had a male and a female up until today, because one would always chase the other around, but today the smaller guy has ben chasing the bigger one.

males have the pointed gonopednd or how ever u spell it. its the pointed thing under there fin and females are arounded

The female will have a fan shaped anal fin, the male will have the gonopodeum(?) or whatever it's called. Like a tube shaped anal fin instead of the fan shaped fin of the female.

Males have a body part that all male livebearers have -- a gonopodium.

It looks like a stick or a shaft at the bottom that is unique to males.

is this a male?

is this a male?

It appears to be so due to the presence of the gonopodium. Platies can be confusing sometimes because certain specimens can look like they go both ways.

Never knew about this! I guess I learned something today! Do other fish have this feature?

A picture is worth 1000 words, from the 2 books I read up on it looked like my plattys were both males and females, but I just looked, and I have 2 males. Picking up 3 chicks tomorrow, all my LFS has.
