Perfect for small fish tanks.

Works great with my betta 5 gal tanks & takes up no room at all in the tank.

Ok for the price. Doesn’t heat well.

Good deal for the price I suppose. It did not heat my tank very well. 2 of my fish died the first day. If your fish are very sensitive to temperature I suggest a heater with temperature control.

No thermostat

I purchased this for a one gallon hospital/Betta tank. The tank is 7" long and this is 5 1/2" long and the price was good. Problem is it heats the water to around 84 F. which is hotter then I would want it and there is no way to adjust the heat on this unit (at least that I know of).Read full review...

Betta heater

My fish was unhappy without this heater. Slides in under the rocks and gently warms the water.
