What is the Best Heater For Betta Fish?

There are many different kinds of heaters for betta fish. You can use an EHEIM heater for a 1.5 to 2 gallon tank, but these can overheat smaller tanks. There are several variants of the EHEIM, including models with 25 to 300 Watts of power. These heaters are great for tanks up to 100 gallons. Another important feature is that they are highly sensitive, and shut off automatically when the water level drops.
