This compact heater works for glass and acrylic aquariums up to 10 gallons in size and will safely raise water temperatures up to 6°F above ambient temperature. The fully submersible design installs easily with the included suction cups and is available in 7.5W and 15 W sizes. Your fish will be swimming pretty in the wonderfully warm waters of their tanks!

Fully submersible, shatterproof construction. Attaches vertically or horizontally with included suction cups.
7.5 W heater works best for 1 to 3-gallon fish tanks; 15 W is best for 4 to 10-gallon tanks.
I like the thin flat shape of this heater. It started to run very hot and was getting too warm for my betta. There is no adjustment other than unplugging it when it gets too warm. I had it in a 2.6 gallon planted betta/shrimp tank with an external filter and full spectrum leds.
I love this heater

I bought this heater in early winter and I am shocked by the negative reviews. I've had zero problems with it. Great for a baby turtle in a small, shallow tank! This helped keep my shellkid warm through the New England winter when two hanging overhead ceramic heaters couldn't cut it. And it truly is shatterproof--you can bend it a little and it doesn't break. Idk about fish but it's great for a turtle
Doesn't warm water

Bought 2 for my turtle tank. I could feel it warmed itself a little but not enough to warm the water. 2 days later it doesn't work at all. Called the help # and they refunded the money instantly. Wasn't expecting that with no hassle. Very impressed with the customer service but not with the item.
Do Not Buy

I thought this would be good for my betta fish tank as one review said but it only raises the temperature 2-4 degrees above room temperature. Bettas need water temperature between 78-80 degrees and this heater only raised it to 72. DO NOT BUY THIS FOR YOUR BETTA! Take the time and put money into a good aquarium heater

This heats my 3 gallon tank 1 degree higher than the 5 watt Aqueon heater I tried previously. Not impressed. I'm skeptical of buying the next size up after reading reviews. It seems fish tank heaters either boil your fish or outright don't work.
Not just for fish

This is for the 15w heater. I purchased this as a way to keep a large (cooking/pasta) pot of water, for the neighborhood cats, from freezing in 20 degree and below weather and so far it's working perfectly.

This heater does not work at all. Water is cold after 24 hours plugged in. I only gave it one star because it wouldn't let me leave a 0
I really like how chewy does business.

My review is for chewy. I was not able to use the heater, my outside outlet doesn't work.
