Lovely, are there any fish inside or is it just ornamental?

Funnily enough, I saw all five only this morning.

I always wondered - what happens to the fish when ponds freeze over in winter?

Rachel Green said...

If the pond is deep enough (over three feet) there's a point at which the water doesn't freeze.

When a pond freezes the densest water is at 4 degress C and that sinks to the bottom of the pond. As long as the pond is deep enough that deepest water is safe.

Because the water is so cold the fish's metabolism slows down, they dont eat or need much oxygen and can survive for weeks.
