Looks good

This heater is great for a small tank. I have a 2.5 gallon tank for my beta. It suctions to the side with two little suction cups. It warms the water, and my fish likes to swim over and snuggle up to it. Only problem is I have no idea how hot it is. It was cheap, so there’s no temperature gauge. I just check the water periodically.

I currently use two of these for two 2.5 gallon betta tanks. The most important thing to know about these heaters are that they do not shut off! They continuously heat the tank just like a simple space heater in a room. Eventually the water in the tank will reach a steady temperature. The final temperature of the tank is primarily based off of 1) The size of the tanks and 2) The temperature of the surrounding air. If you keep your room on the cooler side (roughly 66-70 degrees Fahrenheit) this heater should heat a roughly 2.5 gallon tank to a high-70s/low-80s temperature which is perfect for a betta. It could also work for a larger tank in a warmer room. Aqueon also produces 5, 7.5, and 15 watt heaters for different tank parameters.Other notes:- Extremely compact design- One of my heaters runs about 1 degrees F warmer, though this amount of variation isn’t an issue for me.

Works great! My betta fish is much happier now that the tank is warm. Its a 2.5 gallon tank amd so far has kept it at about 80 degrees.
