Agreed, try to insulate it.Try wrapping it in some blankets to keep it insulated. Besides that you just have to hope for the best. Sorry, and good luck!
You can do water changes with warm water which will also keep your nitrates down. I've lost power for 4 days straight and that's what I did and didn't lose any fish. I also agree with insulating the tank with blankets. Good luck
Power just came back on a little while ago. I've lost some black neons and the rest don't look so good but there alive, can't see any dead CPD's yet. About to start doing a big water change with warm water.
What's the temp in the tank now? I'd just let the temp rise naturally, your fish are already stressed/weak. The temperature shock with the warm water could kill them
