This Jurassic styled piece is essentially a basking platform that safely mounts above tanks, giving your pet a place to dry, to get warm, or just to hang out. This extra space provides a healthier and roomier aquatic environment for your pet. The Turtle Topper is designed for standard sized tanks up to 55 gallons and 13” wide, including 10g, 20L, 20H, 29g, 55g, and more! Within minutes of installing this piece, you’ll notice your turtles gravitating towards it! Ideal for most breeds of aquatic turtles – they’ll love basking out of the water! Secure Mounting: The Turtle Topper utilizes 2 adjustable 1.5” suction cup mounts that lock onto the tank’s walls. For a strong and secure bond, please clean and wash the suction cups with water before mounting, as well as the contact areas at sides of the tank. The cleaner they are, the stronger the bond! Measurements: Overall = 17” x 14” x 10” Inside Basking Platform = 16” x 12.5” Grill Door = 7.27” x 8” Ramp = 5.75” x 8”
