For automatic backup power to come on for a fish tank during an outage, I've seen people use a relay and trickle charge with an inverter and car battery backup. Trickle Charger keeps battery maintained and feeds a relay that is constantly on. Lose Power, Relay disengages and then closes contacts to power 120 VAC low amperage devices like pumps and heaters.
