The temperature is not the problem unless it goes below 70K The tank if large enough will cool down slowly. You can help it slow down even more by floating containers with boiling water if you have someway to boil the water. (your neighbours gas range or your BQ).
The problem is the lack of oxygen which will kill the inhabitants. Whether it is a battery driven air pump or a egg beater, anything that either injects oxygen into the tank or stirs the water is needed.
As well as the welfare of your inhabitants, you have a lot of money invested in the tank. Nothing if worse than a tank wipe out.
Go to Canadian Tire and get what you need.
