Nice pond Leonardo! It's understandable that you love your fish. We all get attached to our "people." Isn't that why we're on this forum?
Where the heck do you live Meat Puppet! Snow 3/4 of the year!!!! Oh my goodness.
You could probably still have an outside pond, you know. I live in Upstate NY and looked into the parameters I'd need to have one here. The frost line goes 3' to 4' deep in the winter, so as long as my pond is that depth, I'd be ok. I also read that I'd need to have some sort of agitation at the water's surface to prevent it from freezing completely on top. If ice forms over the entire surface, the fish will die from lack of oxygen and other gases building up.
::sigh:: Some day.......
