    I read somewhere online that when platies are in adulthood females should be bigger than male. Since my female is smaller than my male is it possible they are still young and have not mature.

    Hello!

    Sexing livebearers are easy, just make sure they are adolescent-adult age because juveniles usually all look female. Look for the anal fin (the single fin behind the butt) and look st the shape. (Btw...I know the pics aren't of platys, but sexing livebearers follow the same rules)

    Males have a rod shape fun called a gonopodium

    Females have it fan-shaped

    Hope this helps and best of luck!

    Yea I know how to sex my platies I wanted to know if they are mature since they are smaller than my male and I read that when female platies reach adulthood they should be larger than the male

    A female from the same bloodline and raised in the same conditions will almost always be larger than a male, or at least more "stocky". That does not mean all female platies are larger than all male platies at maturity.

    what do mean by bloodline like if they are related? and would it be a high chance that female are larger or a low chance

    Oop sorry! Like what @OnTheFly said, females won't always be bigger. If you be had them for at least 3-4 months (4 being the best), then they are mature.

    I've seen similar sized and even smaller female platys. But they usually do get rounder...if that's what u we're thinking.

    It's just like humans. I'm a 5'4" girl. My mom and I are the same height and my dad and brother are taller than both my mom and I. Most family's are like that. That being said, if I go out into the world, I will undoubtedly find a guy who is smaller than me, yet is still taller than his female family members ("same bloodline"). Idk if this helped lol but I'm trying!!

    They could be related, but at least the same strain. Say red wag platy from a breeder in Florida. There is a good chance the males and females will grow to a consistent size, females being larger. Perhaps another strain from Thailand. These fish might be 30%+ smaller or larger.

    Overall, the chance of the largest fish being females is high if you have similar platies from the same source.
