This 8-watt, submersible heater helps create the ideal water conditions for your betta to thrive in bowls and tanks up to 1.5 gallons. It’s designed to automatically reach and maintain a set temperature, which means you don’t need to make any manual adjustments.

Buddy my beta fish is in love with this heater. In the mornings he is cuddled up to it. This heater has made Buddy very happy!
It works but it does get hotter than what it said it would do. Hopefully fish will not die! Temp varies but wondering if that has to do with house temp. too?
We have only had this a couple weeks but it is doing exactly what it is supposed to do Our small glass aquarium is staying at about seventy eight degrees and our betta loves it
It worked for a couple weeks just fine for our 1 gallon tank keeping it at around 76 degrees but all the sudden the temperature has jumped up to 84. I am lucky my fish is still alive but this was disappointing.
Well i'd love to review the heater i ordered but i got a pet safe collar for outside paly instead... not sure how this happened but now my beta fish is still cold but he can go outside safely...
Warmed my beta’s bowl up from 65-80 degrees in a couple of days. He’s a happy fish now!
We use this in a 1/2 gallon vase type aquarium. It works perfectly!!
I was hesitant about the purchase since I had read mixed reviews, but the little heater has worked great for my 1-gal. glass bowl. It keeps the water at a perfect 78 degrees. The only time the water got too warm was when I had a hard plastic covering over the top of the bowl. I removed it and everything was fine!
