Create a natural basking area in your aquarium with the TetraFauna Turtle Island platform. This platform automatically adjusts to varying water levels giving your aquatic turtle the perfect area to bask. This basking surface also includes an easy to read thermometer to help you provide the optimal temperature for your turtles. The floating platform is attached by a submerged ramp, anchored to a weighted base, which allows for easy access to the dry area. This turtle island can be placed in all standard 20, 29, 40, 55 gallon aquariums.
