The Marina Betta Submersible Heater is an automated device that sets up perfect water conditions for bettas to grow healthily. It's equipped with a suction cup, allowing for easy installation on the aquarium glass. This heater is ideal for aquariums up to 5 liters (1.5 Gallons), ensuring your betta has a comfortable living environment.


Using the Marina Betta Submersible Heater is a breeze. First, make sure your aquarium is filled with water. Then, use the suction cup to attach the heater to the inside of the aquarium window. Plug it in, and it will start working automatically to keep the water at the right temperature for your betta. When using the heater, avoid knocking it against hard objects as it might break. Also, don't touch the heater with wet hands when it's plugged in. To maintain the heater, unplug it and clean it gently with a soft cloth every few weeks. This will help it work well for a long time.
