Yes. A 25w will do fine since Betta's should be kept between 76-80. I keep mine at 79

Bettas are tropical fish. You should keep the water between 78-80 degrees. So yes you should use a heater. This is a convenient area for a heater hidden in the filter compartment. It fits typical 25 or 50w heaters.

If you're in a warm environment, I would say No. My apt tends to get a bit cold so I put one in the tank to insure that my beta will be in warm water. The heater can be hidden in the back along with the circulation pump and filter.
