I am going to be getting my first Betta fish soon and I have almost all of the equipment. The main thing that I still have to get is the heater. However, I am struggling to find the correct heater due to my size tank, so I have some questions about them. Firstly, you need to know that I have an 8 gallon tank. I know it’s a weird and unusual size tank and that’s why I’m struggling to find a heater with the correct wattage for the tank. My questions are: 1) Which type of heater is best? 2) How many watts will the heater need to be to heat up the tank? 3)Are there any brands of heaters you recommend?
