Bettas are happiest with a little warmth in their water, and a small bowl can lose heat quickly as the room cools off through the day and overnight. The BettaTherm gives you an easy way to nudge the temperature up, raising it 5 to 10 degrees F over the ambient room temperature so your betta's bowl stays more comfortable around the clock. Because it works in both glass and acrylic bowls and sits fully submerged, you can set it up in whatever home your betta already has without swapping anything out. Drop this submersible mini heater into your bowl, and let it do the quiet work of keeping your fish cozy without taking up much room at all. For fur mamas and fish keepers caring for a betta in a compact home, it is a simple, sensible addition that fits right in and earns its keep.
