Koi and my first pond

[mshill90]

really koi can survive in 20-30 F degree water? so you mean they still alive if the pond with frozen solid water?
usually when the water in the top of the pond froze, the water under it still more than 32F and higher at deeper. The water will be about 39F at maybe 4-5 ft under the ice( I'm not sure, its been a long time since i read that). Koi always like pond with strong currents, so if your pond have strong water current flowing the ice will be thin or may be no ice depend on how cold it get!

Haha, sorry- my bad. I meant they can survive in temps that low, but of course the water can't get below 32!

Koi-cicles.. Yummy!

Take Caution with current... too much current can stress them out if there are no calm spots in the pond.
