mild winter conditions

[Duncan]

All you guys feeding your koi with unheated ponds because it so mild and the temperatures are 10 and slightly above watch out for infections, it may seem great but its a bad place for the koi to be, their immune system is not working but for the pathogens its party time, they are still at their best and cant believe their luck
so keep a careful eye out for early signs of ulcers and parasites at least till the temp drops right off
