Is it yours? Looks good to me.
IMO, this kohaku has a good balance pattern, beni ok, body confirmation and girth are there, I will prefer its to put on more weight. Ideally, lenght at this age is >75cm, but don't really matter, so long is health and nice. Oops.. yes..Its look like a he for me? I don't think I can find one better than this in my pond
