Exo Terra Turtle Bank Island Medium PT3801 – Floating Basking Island

The ET Turtle Bank Island Medium (PT3801) is a magnetic floating basking platform designed for aquatic and semi-aquatic turtle setups. It gives turtles a stable, accessible dry area to bask under heat and UVB, which is essential for thermoregulation and shell health — something a flat rock or makeshift ledge simply cannot reliably provide.

Magnetic Positioning System

The island is held firmly against the terrarium glass using included magnets, allowing you to position it in a corner and reclaim as much open water as possible for swimming. There are no suction cups to fail or clamps to scratch glass — just a clean, secure fit that stays where you put it.

Automatic Water Level Adjustment

As water levels rise or drop, the platform adjusts automatically, keeping the basking surface consistently above the waterline. This removes the need to reposition the island every time you top up or change the water, and ensures turtles always have reliable access to a dry surface.

Submerged Entry Ramp

A built-in ramp extends below the waterline, giving turtles a gradual, low-effort route out of the water and onto the basking area. This is particularly important for younger or smaller individuals who may struggle to haul themselves onto a steep or abrupt surface.

Compatibility and Sizing

The medium size suits a wide range of aquatic turtle terrariums and can be used alongside other sizes of the same island within a single setup, useful for multi-animal enclosures or larger tanks where one basking spot is not enough. It integrates cleanly into existing aquatic terrarium arrangements without major reconfiguration.

For any keeper maintaining aquatic or semi-aquatic turtles, a reliable basking platform is non-negotiable. The ET Turtle Bank Island Medium delivers a practical, well-engineered solution that works with your setup rather than against it.
