Aqueon® Submersible Aquatic Flat Heater (15 Watts)
I'm Chad, the owner of More4less. The number one pain point for any owner of a beautiful Betta bowl or a small desktop aquarium is the heater. Standard heaters are too bulky and, far worse, too powerful, creating dangerous temperature swings that can harm your fish. That’s why I specifically curated this Aqueon Flat Heater. It is the perfect solution—a compact, low-wattage, and completely safe heater designed specifically for these small aquatic environments.
- Perfect for Small Tanks: The 15 watt aquarium heater is ideal for desktop aquariums and bowls up to 5 gallons.
- Consistent, Gentle Heat: Pre-set thermostat automatically maintains a stable, safe temperature.
- Completely Submersible: Slim, flat design can be discreetly hidden under gravel or behind decor.
- Durable & Shatterproof: Thermal plastic housing is far safer than traditional glass heaters.

Expert Insights
"An Aquatic Biologist specializing in nano aquariums and Betta care would stress that temperature stability is the most critical factor in a small tank's success. The reason this Aqueon flat heater is a superior choice is its low wattage. In a small volume of water, a high-wattage heater creates a rapid 'on/off' cycle that leads to constant, stressful temperature fluctuations. A low, **15-watt heater**, by contrast, provides a gentle, more consistent heat that mimics a stable tropical environment. This consistency is absolutely key for preventing stress, which is the number one cause of illness in Betta fish."
Designed for Your Smallest Aquariums
This heater is built from the ground up for desktop tanks. Its ultra-slim profile is designed to be fully hidden, maintaining the beautiful aesthetic of your aquascape. The shatterproof construction gives you peace of mind that a simple bump during maintenance won't lead to disaster. For anyone wanting to create a healthy, stable, and beautiful home for their Betta or other nano species, this **small tank heater** isn't just an accessory—it's the most important piece of equipment you can buy.
Installation Guide
- Place the heater in your desired location in the tank. It can be placed vertically, horizontally, or even buried under the gravel.
- Wait 15-20 minutes to allow the internal thermostat to acclimate to the water temperature.
- Plug the heater into a power outlet. The LED indicator will turn red when it is actively heating.
- Always use a separate, reliable thermometer to monitor your tank's water temperature.

Frequently Asked Questions
Is the temperature on this heater adjustable?
No, this is a pre-set heater. It has an internal thermostat designed to automatically maintain the water temperature around 78°F, the ideal temperature for betta fish, without requiring any user adjustment.
Where is the best place to put the heater in my tank?
It can be placed anywhere, but it works most efficiently when placed in an area with some water circulation, such as near your filter's outflow or an air stone, to help distribute the warm water evenly throughout the aquarium.
