Are you saying that a koi would have to be least 3 years old before I would be able to tell about body
At that age would the body not already be their.? Would not a wide tail tube be a sign, and is this not present in small koi. Say 6 inhes. I think I know what to look for in tail section as far as it being full and wide, and thick. Large pec fins I thought is a sigh of a male. Wide shoulder and thick tail tube way a sign of a female. And of course a big head If you want a big koi and you look for these sign would you be always buying female?
