From Watts to Tank size.
Some of the things to consider when getting a heater are to know if it’s able to put out the right number of watts to continuously heat the tank.
A heater would ideally put out 3 to 5 watts per gallon of water. Therefore, if you own a 5-gallon tank, you would need a heater that provides between 15 and 25 watts of power. It’s possible to use two heaters if one can’t do the job effectively.
The whole essence of having a heater is to be able to heat the water tanks and be able to read the temperature while at it. it is always important to go for heaters that are readable temperature-wise.
But you need to understand that the temperature reading on your heater isn’t going to be accurate all the time. that is why you need an extra thermometer.
Heaters are mostly placed in the tank, being plugged means there is going to be a lot of electricity. But these companies that manufacture these heaters know this.
That is why the majority of the heaters are designed to be safe both for the betta owners and more importantly, the betta owners. You should look out for heaters that have all the safety features you need.
There are two types of heater out there. One type of heater has a fixed temperature that can’t be changed and the other one has a temperature that is variable and can be adjusted necessarily.
Normally, the lower cost tanks are likely to have a fixed temperature which can’t be changed. You should get the one with adjustable temperature so that you can vary the temperature with the change of weather.

There are different ways of fixing a heater, it all depends on the particular heater. The design of a heater determines if it will be placed vertically, horizontally, both ways in the tank. You need not worry about this as the manufacturer will clearly state this in the package.

To be surer, you should read the instruction manual before handling the heater.
