Starting to snow here now and pray you don't lose power. My chimney runs on gas, so that is the back up plan for a Winter power loss at home. Still, would have to transfer all frogs to temporary containers and move near the heat source. Sadly, the fish would be on their own heat wise; because they are to big to get out of tanks . I do have battery powered air pumps with lot's of D cells for aeration.

Thank's for the info on the heater Gail! The fact that one can be used inside house safely, makes it real handy for an emergency .
