Being someone who lives in the hot tropics without 4 seasons, this is a very intriguing topic. We don't have a winter season to stop feeding the koi, and if we cut down feed too much, the koi will lose bulk because the warm temperatures maintain high activity and metabolic levels.
Momotaro koi are known for their big potential size as well as being very fast growers. Apparently the knife cuts both ways and many have lamented that they have shorter average life spans too, as a result. Is there any evidence to this effect or even just a gut feel?
Sometimes it's not a matter of being impatient for rapid growth, but the fear that if the koi does not get its best possible growth during its 1st 3 years, it will never achieve its maximum genetic potential for eventual size.
Cheers,
