Happy Heater

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 too Well!

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?

Works well

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

ok at first then got too hot

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.

Works great!

Warmed my beta’s bowl up from 65-80 degrees in a couple of days. He’s a happy fish now!

Small Betta tank

We use this in a 1/2 gallon vase type aquarium. It works perfectly!!

Works for me!

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!
