      Am seeing two things on your pictures that one leads me in one direction and the other in a different direction, could you please answer my question: how old is this koi and what's the length? Thanks in advance

      Latest pic, an earlier pic?

      Have you run your fingers over the gills entry water points, or the leading edges of the pecs or the pectorals fins for a sand paper

      effect?

      Have you attempted to draw milt?

      Your latest pic appears to be a younger fish

      I still stand my by original observation of the first pic you displayed!.

      My guess. A male. The female vent is slightly protruding or convex and pale pink in color while the male vent is flat or concave – this is the definitive way of sexing a koi. The vent looks concave. Body is slim.

      Folks look at the leading rays on the pectoral fins and tell us what you think.

      Compare a male and females peduncle.

      The males peduncle is slender and tapered down, from the rest of it's slim body shaved down to the tail fin for speed and very quick movement,

      turns on a tickey.

      This female is designed for strength, to carry in it's bigger abdomen,a bag full of roe,eggs to be laid when the eggs have matured enough to

      be laid and dispersed, to come into contact,with a cloud of sperm, distributed by a fast moving male, darting in and out the other

      male competition, attempting to spread their DNA.

      Over a few days the fertilized eggs develop into a minute fish ready to hatch out of the egg shell, which is bonded to a surface from where

      they can break out of their shells and become free swimmers.

      I see a crosswise slit in the vent, I'm guessing female.

      In all honesty - very few of us have the ability to grow koi to their full potential so the M/F thing really doesn't matter.

      I am not sure this large mature koi looks like any of those. I've had it 10 years and still am not sure. This is the same one we discussed at https://www.koiphen.com/forums/showt...ht=male+female
