The most important decoration in a turtle enclosure is the basking area. It should be large enough to fit the turtle with some room to turn. The basking area should always be in line with the water level to ensure that your turtle can get out easily, there are floating docks available that will reposition to match the water level. A good basking area will also include a ramp for the turtle to make it easier to climb. Artificial plants are a great way to provide cover under water and add colour to the enclosure. Those with weighted bottoms can be fully submerged whilst light plastic decorations can be left to float on top. Giving the turtles partial cover and a mixture of weighted and floating decorations provide great enrichment and help the turtle feel secure. Large pebbles, coated gravel or riverbed sand can be used to line the bottom of the enclosure. It is advisable to clean any substrate before placing it into the enclosure. The substrate should be left to settle before the equipment is turned back on and the turtles are put in.
