Interpet Aquarium 15 watt heater for up to 4 gallon tanks
I have tested this and it works to heat up the tank but ONLY up to 9°F in room temperature water. It's good for temporary tanks (like putting your fish in a seperate tank when sick or cleaning their main tank). 

Definitely would make sure the environment is still warm around the Aquarium if you do use this, but definitely not for colder rooms as it doesn't put much heat !!

I've made sure to clean this without using any harmful chemicals, strictly filtered water. It also did not come with a thermometer as it states on the box. If you have any questions, feel free to ask me!
