Not a chance to evacuate the tropical fish in a non tropical environment.
Can't take the heater.
Can't take the filter.
Can't take the air pump.
They need all of the above to be alive for more than a few days.
Without a heater, the tropical fish will freeze to death.
Without the filter, any fish will die of ammonia poisoning.
Without the air pump, the fish might die of oxygen starvation.
Basically, it is no good to take the fish with you if you can't provide constant source of power to run those equipments.
Cold water fish like goldfish might live a little longer under the same situation, but won't live for very long.
You can keep fish in plastic bin, as long as you have a cycled filter system, and a heater if they are tropical. Air pump is needed if the water temperature is quite high.
I know some people who use trash bin to store water for the next water change.
