Therefore, you should look for safety features in the product you are choosing.
A betta tank heater also needs a lot of flexibility to be easily installed in the tank.
Look for products that you can place horizontally across the bottom of the tank, or maybe vertically along the tank. For small sized tanks, you should choose the heater that can hang in the tank.
And you should also choose devices that come with a stand or suction cups so that they can be fixed easily.
You should choose a heater that can allow you to adjust the temperature range easily. So you can change the temperature of the water in the tank to a level that suits betta better.

Choose equipment made from durable and strong materials, which can resist rust and not affect betta.
Materials that are resistant to high pressure and impact-resistant and not easily destroyed should also be a preferred option.
