But it's hard to get a decent heater for your
small tank.

6", 25W, unbreakable heaters are available. The trouble is they cost
more than the tank!

And if they stick on, they can overheat a 5 gallon tank in short order!

Despite the "common wisdom" that specifies 5wpg, I put 2-3wpg in my tanks.
They seem quite adequate and give me a bigger safety margin if they stick in
the on position, which I understand is the most common failure mode.

And a 10-15 watt heater for a 5 gallon tank is not, AFAIK, available. There
is a tiny permanently on heater but it gives a water temperature related to
room temperature. If you set your thermostat down at night, as we do, the
tank temperature goes down as well.
