Highlighted Reviews
"I bought this heater for my beta fish who lives in a 3 gallon tank. It's perfect. I was worried about him when the colder months came around and he started to become inactive, but he perked right up after I added this heater to his tank. He loves to hang out near it when it firsts turns on. "
