Rated 3.8 out of 5★by 78reviewers.
Rated 5 out of 5★by Small Heater for Small Tanks Locating an aquarium heater for a tank less than 10 gallons is no easy task; the majority of heaters aren’t designed for smaller aquariums despite their continued popularity.I chose the Tetra Whisper Heater 2-15 gallon model for a few reasons; 1) I’ve used Tetra products over 25 years, 2) Its compact size of 4.75”. There is no thermostat; the heater is designed to maintain the water temperature between 76-80 degrees. I have monitored the temperature in my 5 gallon Mini Bow over several days, the temperature has evened out to 79 degrees. It is safe for acrylic tanks (I checked before purchasing), is completely submersible with the option of vertical or horizontal positions and contains a indicator light to let you know its working.I am quite pleased with this little heater and I’m sure my Betta (Indiana Jones) is thankful he won’t be subjected to temperature fluctuates that could lead to illness. 11/02/2008
Rated 5 out of 5★by Great product I have used 2 of these heaters for the past 3 years and they have both been great. The heater does a good job of keeping up the temperature. I know this for a fact because my fish have been healthy and have lived long lives. I also own a crayfish and it has molted which is a good sign that the water is at the right temperature. Many people are reporting that it does not raise the water temperature to what they want, but that is probably because they are checking the temperature of the glass on the outside. You should dip your finger in to see if it's warm to decide because the glass will always be cooler than the water. This heater also has a small red light that glows when it's heating the water and it turns off when the water has maintained the right temperature, so don't take it as being broken. If you want to check to see if it's still working, place it in a cold bowl of water and plug it in. If it works, the red light should glow. 08/31/2010

Rated 4 out of 5★by good little heater I got this to put in a 6 gallon tank. It keeps the tank at a steady temperature of 76. Overall, I am pleased with the product. 04/29/2009
Rated 5 out of 5★by GET IT! This heater is great for my 2.5 gallon Betta tank. it keeps my tank between 78-81* its wonderful, and my female loves to sleep on it :)~ its tough and dependable - love it! 12/20/2010
Rated 3 out of 5★by Proper prep not in instructions! Like a few reviewers, I've had issues with this heater. I came back to read the reviews and I realized that in the directions nowhere does it say you should let the heater acclimate to the water before turning it on. I unplugged it for 30 minutes (while submerged in water of course) then plugged it back in, and within an hour the water in my 10 gallon tank was reading 76*. So if you have this problem try unplugging it and letting it sit for a bit before turning it back on. 01/27/2014
Rated 1 out of 5★by Doesn't Heat Water Properly I breed fish and some of the tropical species need the warmer waters in the high 70's to low 80's. I purchased this one because it seemed like a good value. The heater says it heats up to a 15 gallon tank to a constant temperature of 78 degrees. Unfortunately that is not the case. I had it in a 10 gallon tank for an entire week and it never heated the water more than 74 degrees. The last straw was when it let the temperature fall to 72 degrees. 4-6 degrees doesn't sound like a big deal but for fish it's a deal breaker. For the same price I found one at pet store that you can manually change the temperature on. For the beginning owner that just wants to keep a couple hardier species of fish this product MIGHT be okay. But for anyone that really wants their fish to thrive I'd pass on this one. If I pay for a product that says it heats to 78 degrees then that's what I expect. Very disappointing product. 04/22/2013
Rated 5 out of 5★by Does what it says It keeps the tank at 78 degrees plus or minus 2 degrees, doesn't take up much space, little red light says its heating, suction cup works nicely, unplugged now it's summer though 06/03/2013
