    popping the question again as he/she has changed quite a bit. Boy or girl?
    It’s tail is a lot more colorful with more pattern then my full grown females. It’s is getting some spots too which makes me think boy, bu the top fun looks tall so I’m not sure. I couldn’t get a good still so I took a couple short videos of it swimming but couldn’t post them so here are the best screen shots...

    I can't see the gono in the picutres. But I would say male. The coloration and body type looks like male.

    If he has a straight, pointy fin underneath his belly, he is male.
    If the fin underneath his belly looks like an actual 'fin'. and is triangle shaped, she is female.

    But I'm almost 85% sure that he's a male.

    I think it's a she but as fishgirl said you've got to check under the belly for a straight pointy fin
    If it's there it's surely a he

    Wow it is really hard to see the vent fin in those pictures. Even when I enlarge them I think boy in one pic and girl in the next.. Is there any way to can get a slightly closer and perhaps clearer shot? I know this is not easy.

    @Fishbeginner01 - yes those pics are a LOT better.

    From these pictures, you can see that the anal fin looks like a stick. This is called the gonopodium (male reproductive organ). Its a BOY!!!!!

    a girls fin in the same location would be flat not round.

    The females anal fin will be fan or triangle shaped, the males is like a rod. Tail color doesn't mean much with the fancy guppies now. Sex by the anal fin and you won't be wrong.

    Yea it's surely a boy
    The gonopodium is much easier to see
