Any fish will suffer. A lot of ours are dead in a 1.5m pond anyway
after these frosts.
What normally does for the fish is lack of oxygen rather than cold.
If you had a solid layer of ice covering the whole surface area the
oxygen levels could easily have dropped too low. Many pond owners
have a small heater which keeps just a tiny patch clear, we have a
fountain which does the same although in the last big freeze-up it
only managed to preserve a very small patch.
The other problem can be frogs. They have a nasty habit of dying in
the cold and decomposing in the water which poisons it.
I wonder if the filter has frozen?
Plays havoc with small ponds if you don't have a good filter 24x7.
Mine hasn't frozen yet even in these cold spells.
what filetr?
This is just a hole in the ground full of water mate.
about 3x5 meters and about 2 meters deep. at its deepest.
