|46 ratings

Key item features

  • Mini Size: The heater is only 4.5” in length making it a great choice for small sized tanks from 3 to 5.5 gallons without taking up much space and obscuring the viewing area.
  • Easy to Use: The small 25W aquarium heater is preset to 78°F which is a perfect temp for Betta and most of other tropical fishes, and no extra setup needed just plug and play.
  • Easy to Check: The indicator light turns red when it is heating and it turns green when it is resting so it is easier to do a quick check every day.
  • Includes: 1x 25W Small Aquarium Heater, 1x Suction Cup, 1x Free Thermometer Strip
  • Cautions: Always keep it fully submerged under water before plugged in, and unplug it and wait for at least 10 min before you do aquarium maintenance or take it out of water.

Easy to set up and my fish is very happy

Actually it's 4.5 stars because the little sticky thermometer doesn't work. However, the heater itself is great for a small tank. Seems to be regulating the temp well (again, not sure because see above) but my fish seems much happier. Easy to use and it arrived carefully packaged.
