| Hi Teh, my understanding of "jumbo tosai" is different from yours. To me jumbo tosai simply mean that these koi are larger than their fellow brothers & sisters. They are able to grow faster in short time-frame but that doesn't mean they can guarantee grow up to 85cm & above even in a lightly stock big pond with state of the art facilities. The offspring of a 96cm former multi trophies winner in Japan nickname 'Snowhite' gave birth few month back here. Those hobbyists who were qualify enough by the dealer to purchase the top tosai in the offspring can only hope to raise them to jumbo but no guarantee too even with their experiences & skills. I'm a real tosai only in this hobby for a mere 9 months. I'm mostly incorrect. The Japanese might have their original version of 'Jumbo tosai' which I do not know at the moment. Feeding Hikari excel might not be good for long period of time but that is still base on assumption. I'll continue to use it untill one day I notice something unusual happen to my koi or cause them to have unusual behavior. Sure will be heart broken but got to do what I got to do. SF |
