Small Aquarium Betta Heater, Submersible Fish Tahk Heater 10W/25W/50W/100W with LED Digital Display, Suitable for Marine Saltwater and Freshwater up to 5/10/16/26 Gallon

Complete waste of money. It is a US product that is not compatible with Indian voltage parameters. was informed by the seller one day before delivery. Highly unprofessional behaviour.

I am just starting my first proper Betta aquascape and this heater is fantastic. Its small, easy to set up and a great price.

I’m extremely satisfied with this water heater. It’s the perfect size and does an excellent job heating the tank efficiently and consistently. The heater shuts off automatically when the set temperature is reach making it safe for the fish. The only improvement I would suggest is the ability to calibrate the thermometer, as it appears to be off by a few degrees. That said, considering the price point, this is a minor trade-off and doesn’t take away from the overall performance. Overall, a great value and a solid choice.

Quality product for the cost! Helped my fish from dying in the cold water from my AC!

Consistent temperature

I can't express how thrilled I am with the hygger Small Aquarium Betta Heater. It's been an absolute game-changer for my betta fish, and I'm convinced it played a vital role in his recovery after falling ill. Before getting this heater, I struggled to maintain a consistent water temperature in my 10-gallon tank, which was especially challenging for my sensitive betta. But since I started using the hygger heater, the results have been great. The heater is easy to install and operate. It's submersible, which means it doesn't take up valuable tank space, and the temperature control is pretty accurate. My betta now enjoys a consistent, warmer water temperature that has visibly improved his overall well-being. It comes with all the parts you need and a user manual. It's easy to operate and my fish is happy!
