If I were picking tosai, this is a koi that I would likely avoid because of the look of the beni. The beni shape suggests the beni was in the process of disappearing. That could have been what was going on but you and your pond seem to have stopped the process or slowed it down to a point that the loss of beni was insignificant after one growing season. Do you have soft or hard water? What is the water temperature range during your growing season?
Again, good job raising the fish. I have found that Momotaro fish are rewarding to keep due to their genetic tendency to grow large while maintaining their youthful look.
