I bought these for my 2.5gallon killifish tanks. These heaters take up very little space in the small tanks, since they are flat.

But be aware that these heaters don't have temperature controls, so the water temperature will change when the room temperature changes. My tank temperature ranged from 92F to 70F with the heater plugged in from May to December. I had to unplug the heaters on very hot days. It seems that these heater will raise the water temperature in a 2.5gallon thank by 8 to10F over the room temperature.

Finally, all 6 mini heaters that I own have been reliable for 8 months now, and all are consistent in how much they heat the same volume of water.

I purchased this heater for our beta who lives in a 1 gallon jar; note the heater is spec'd for 2 to 5 gallon containers. During the winter we keep our house at 60 degrees and this heater keeps the jar at a consistent 72.

4.0 out of 5 stars Good heater for tiny tanks., March 8, 2007

This heater works well, not bad for small tanks (5 gallons or less). I purchased this for my 1 gallon tank, and it heated the water up to the low 80s. The heater works submerged or placed under the tank. I keep my apartment on the cool side, so this heater did the trick. A word of warning, though--if you have a 1-gallon tank, make sure you have a thermometer in it, because if you keep your home temperature in the high 60s and into the 70s, chances are the heater will then heat the water too warmly, into the mid to upper 80s, at which point you'll have to unplug the heater and monitor the temp as needed. Still, not bad for the price.
