Thumb-Sized 15W Super Mini Aquarium Heater with Digital Display brings trusted quality to your fish care routine and ranks among the best-reviewed items in aquarium temperature controllers.

Key Features

  • SUPER MINI SIZE – This mini fish tank heater is just about the size of a finger. It's fantastic for nano tanks/betta tanks. The groundbreaking super tiny design brilliantly addresses the fish keepers' annoyance with traditional heaters!
  • ALUMINA CERAMIC - This betta heater is made of alumina ceramic. Built for unmatched durability, it features super mechanical strength, enhanced heat and chemical stability, and superior electrical insulation.
  • PRECISE TEMPERATURE – Courtesy of sophisticated inverter technology, with its in-built chips, this thermostat maintains the heater at a steady temperature with an accuracy within 1℉, a lot more precise than conventional knob-controlled heaters.
  • OVERHEATING SAFEGUARD – Safety is our paramount concern. With its safeguard, this small aquarium heater will stop functioning when the water temperature surpasses 97F. No more worries about "cooking fish"!
  • MEMORY FEATURE – The most recent setting is saved in the thermostat. In case of a power outage, the small betta heater will revert to the last setting once power is restored.
  • VERSATILE USES – This betta fish heater can be used in both fresh and saltwater. Not only can it serve as an aquarium heater, but it also works well for turtles, pet fountains, and plant seedlings.
