Water fountains in winter

I have a small solar pumped water fountain in my pebble fountain. Temperatures have dropped (we had snow on Wednesday) and it's only just occurred to me ...


... should I put it away at this time of year?

I've had the main pond netted against leaf fall this time of year, but I haven't worked with a fountain before.

TIA

 

I would with a small one so it doesn't freeze and crack!

 

Thank you, catz
