When buying koi is it better to buy larger/older koi
Or smaller/younger koi?
Not based on cost.
Whats is the benifits of each in your experience
Thanks i know its a silly question to experts like you but there is no point in spending money on lots of little fish who will not turn out like you expect or struggle to survive when you can spend a little more if they are stronger and fully developed.

In general for successful growing on of small fish you will require heating.. Small 6"-10" fish will struggle to survive a first winter in an unheated outdoor environment. Larger fish are generally hardier so would be more suitable in unheated conditions.
Lastly the behaviour in the pond is different. Smaller fish tend to be skittish and dart here and there whereas larger fish take on the more graceful, slower swimming pattern.
Back to the beginning - personal choice is the main player.

This never really happened as most died over winter or the subsequent spring so I only buy 8-10 inch and above.
