Getting the right stove shouldn’t be a problem as there are so many available today. In this guide, we will learn more about such stoves and their general benefits.

A tank heater is one of the most important pieces of equipment you will need to keep your betta fish healthy.

Bettas are adapted to tropical waters, which are usually slightly warmer than room temperature in your home.

You see, the temperature in your home is not as stable as the temperature in the natural environment of Betta; it fluctuates up and down depending on how hot or cold it is outside.

A tank heater can compensate for those differences by keeping your aquarium at a constant warm temperature.

But choosing the right heater for your betta fish can be challenging, especially since many inexpensive heaters in the market don’t perform as well as advertised. Today we’ll take a look at the features to consider in a betta fish warmer and discuss five of the best Tank Heater for your betta fish.

Talking about one of the most important devices you need to create a favorable environment for your betta fish and keep them healthy, the stove is a perfect example of this “important equipment”. In this piece, we’ll be sharing with you the 10 best Betta Tank Heater available today!

Does a Betta Fish Need a Heater?

To help answer this question, you must first know the importance of a heater. Well, the main reason is that fish can be a delicate species. By having the water at the right temperature, you can be sure they are safe.

It is not just about the right temperature, but also about a constant temperature. The fish does not have to be in water whose temperature continues to fluctuate.

In most cases the water temperature is affected by the air around the tank. Sometimes this can lead to fluctuating temperatures. To find out, you need to find the right betta tank heater.

Studies show that every time the water gets too cold, it affects the betta fish. They tend to remain inactive. In such a scenario you will see that they have trouble eating, swimming and that some may even die.

That said, you can also expect them to have some health complications if the water is too hot. That’s why you need to keep the water at the right temperature.

Ideal Water Temperature for Betta Fish Tank

So what’s the right temperature? For betta fish, it would be ideal to keep the water between 74 and 82 degrees Fahrenheit (23-28 degrees C). It is often recommended to buy heaters that do not overheat beyond this range to protect your fish.

It will be great if you also have a thermometer. This is because some boilers do not have a current temperature display. Having a thermometer is great for keeping an eye on the heat of the water.

Some also look at the boiler manufacturer’s rating. This helps a lot so you know what temperature the model can operate in before buying.

5. EHEIM Jager Aquarium Thermostat Heater (2nd Pick)

The EHEIM Jager Aquarium Thermostat Heater offers the same versatility as the Fluval E Heater, with a few key differences.

Most notably, this heater can withstand colder temperatures of up to 65 degrees, which is ideal if you live in a warmer environment where the purpose of the heater is primarily to keep the water temperature constant.

Like the Fluval E, the 300 watt version of this heater is suitable for tanks up to 100 gallons.

Note that this heater is significantly longer, at 20 inches, so your tank should be shaped to allow the heater to remain fully submerged. EHEIM also makes smaller versions of this tank heater up to 25 watts, which is suitable for small 5 gallon tanks.

The temperature control on this stove is easy to read and turn as it is located on the top of the unit. The temperature can be changed in 0.5 degree increments at a time for precise temperature control.

The stove has a simple light to indicate whether the stove is working or not. But unlike the Fluval E heater, there is no digital display of the current temperature in the tank. Therefore, you should keep a thermometer in the tank to monitor the temperature and check the tank for deviations from the set temperature.

However, when it comes to safety, this stove stands out. The heater will switch off automatically if the water in the tank becomes too low and a safety check prevents the heater from running dry.

The stove is also built shock-resistant and unbreakable. A supplied mounting bracket and a set of suction cups make it easy to place this heater anywhere in your aquarium.

6. Fluval M Submersible Heater

• Available watts: 50-200
• Tank size: 15-65 gallon
• Temperature range: 66-86 degrees
• Automatic shutdown: yes

This fully submersible heater from Fluval is a cheaper alternative to the E heater, although it loses many of the advanced features of the E heater, such as the LCD temperature display.

The stove has a limited temperature range of 66-86 degrees, so you may have to choose a more powerful stove if your house is often cold. The temperature can easily be changed in steps of 1 degree using the rotary knob on the top of the heater.

The stove is relatively easy to install. The heater comes with a simple mounting bracket with which you can place the heater anywhere and you can remove the heater from the tank without removing the bracket.

Better yet, Fluval has designed the heater to be completely shock resistant and while there is little protection from the hot center, your beta fish cannot make full contact with the heating elements.

Note that although this stove is relatively small, it is still 11 inches long. That means it doesn’t really fit many of Fluval tanks under 15 gallons, such as the EVO Reef 13.5 or the 9.5 gallon Flex tank. Therefore, you will need a relatively tall tank to use this heater and keep it completely submerged.

7. Aqueon Pro Heaters (Best Budget Option)

• Available watts: 50-300
• Tank size: 5-90 gallon
• Temperature range: 68-88 degrees
• Automatic shutdown: yes

This sleek and efficient stove from Aqueon is designed for simplicity. The knob on the top of the stove is very easy to access and the temperature dial is large enough to read.

While you can only change the temperature from 68 to 88 degrees in 1 degree increments, that should be more than enough versatility for most betta tanks. The stove does not have a temperature reading, but there is an LED light to indicate when the stove is on.

The heating element in this stove is well protected so that it doesn’t endanger your betta fish, and the stove itself is designed to be nearly indestructible. The stove also has an automatic shut-off to turn it off in case it overheats, and it will automatically turn back on after it cools down.

A set of suction cups makes it easy to install this heater horizontally or vertically, but keep in mind that the 19-inch length of the heater requires you to have enough space in the tank.
