I asked when I first got it on here the sex it was suspected female. Can someone explain to me the difference in males and females I’d like to find it a mate and I’d like to be sure on sex.

Hard to tell. How big is it? It might be too early to sex.

As far as I know the main differences will be body shape and odontodes.

Shape here looks more like male to me, possible it's too young to have real odontode growth.
 
Still hard to tell size with one fish at an angle and not sure how much further back your L200 is.

Body still looks male to me. I'd expect a female to have a thicker midsection.
 
I'd say 95% sure it's a female. Usually by 4-5" you can easily see the odontodes of a male.
