Still up checking on mine too! One of them actually went inside the house willingly! I couldn't find him, had to bring out a flashlight just to peek in and see that he was okay. I corralled them to within 4 feet of the lamp, and haven't seen any shivering, so I really think they're all right. The outside thermometer where they are is reading about 5 above at the furthest point from the lamp, so that's the coldest they can possibly be, with obviously warmer temps closer to the lamp.
I would say I can't believe yours are in the water at 19 degrees, but mine were skating on the ice the other day in their pool trying to get in the water, and when that failed they "bathed" in the snow, lol.
