Hello Nicole,

We have received your recent product inquiry regarding a NT-25W. This unit is rated for aquariums between 5 and 10 gallons. We feel this unit is too powerful for you 3 gallon betta aquarium. We have another option. We carry a smaller unit which is better suited for you application. It is called the NH-15 and is 5.5" tall; very tiny. Below is a link to the product page.

If you are still interested in the NT-25W the units height is 6" tall.

If you have any additional questions please do not hesitate to ask.

I have a 55gallon aquarium set up for frogs: 40% of it is 'land', there is an acrylic separator that prevents water & soil from mixing. On the 'water' side there is about 3" of water, but the cubic gallons are somewhat less because there are quite a few rocks & other hiding places.
I need a water heater with a preset thermostat, but because of the shallow water I need something that is not mounted vertically, and preferably, not huge. I also have a circulating pump & submersible filter running. Any suggestions much appreciated.

Hello Judy,
We have the perfect heater for your system. The NT-25 NanoTherm heater will work quite well for your tank and it can be installed vertically or parallel to the bottom without any problems. The unit is small: diameter is ¾” and length is 7”. Aquatop offers a smaller 15- watt unit (5.25” long); however, we don’t recommend using a 15 watt heater in a body of water larger than 7 gallons. Assuming your tank is 48 inches long and about 18 inches deep, an approximation of the volume of water is about 6.5-7 gallons. The 25 watt NT can be used in about 10-15 gallons of water with good efficiency. Feel free to call us anytime with any additional questions.

Thank you!
