hwong, you do have a good eye (and a good friend in Dr. Teh for giving you the final nugde on this one

) His Koi selection and keeping skills are well respected by many and by me in particular. She does have a great body, and when one considers the 365 day growing season her sumi and beni look exceptional to me. It takes fantastic water management, the right feeding regime, and a pond with plenty of room to swim to handle that kind of growth well.
Your new pond should give her plenty of room to move and grow, and hopefully it will keep her well for many years to come.
If I remember correctly you have a Bakki shower on your new system similar to Dr. Teh's don't you? Also, will you be continuing Dr. Teh's same feeding regime with spirulina and silkworm?
