What can I do to keep my amphipods warm in the tank. My electricity is currently out and my heater broke. I am getting a new heater by tomorrow morning, but, I am at a loss here as my water temperature is sitting at about 65 degrees currently. This is my refugium so there are no other fish in the tanks at this time. I am growing live plants and etc. I cannot get a new heater tonight, because I am an hour away from any stores and I live in the country so there is nothing around close that stays open late. Any help would be appreciated.
