This Floating Pier doubles as a Basking Platform, and floats slightly above the waterline inside your tank. This feature allows your pet to rest and eat outside of the water. The Basking Platform will rise and lower with your tank’s waterline. In addition to providing a better view, the pier also allows for more interaction between you and your favorite friend! Great for Turtles, Crabs, Frogs, Newts, Salamanders, and many more! Secure Supports: The pier’s platform rests upon 3 pylon supports that are attached with suction cups, which connect to the bottom surface of a tank. For a strong and secure bond, please clean and wash the suction cups with water before placing them inside the tank, as well as the contact areas at the bottom of the tank. The cleaner they are, the stronger the bond! Easy Access for Pets: The textured docking ramp allows your pet to easily climb onto the upper level of the pier, and also features an E-Z Slide design, allowing for it to be mounted at different positions on the front side. Decorative & Naturally Inspired: In addition to serving as a basking platform that allows your pet to dry off and regulate temperature, the Reptology Floating Turtle Pier also satisfies their instinct to hide and rest underneath. This piece is great for terrariums and other reptile habitats that don’t have water. Additional Info: The Reptology Floating Turtle Pier is designed for tanks that are 10 gallons or larger. The Basking Platform will rise and lower with your tank’s waterline, and measures 11.5” x 9”. The Large Size (REP601) comes with 3 Extension Pylons, and with them, the height range becomes 3” – 12”.
