The yellow-bellied slider (Trachemys scripta scripta) is a land and water turtle belonging to the family Emydidae.Yellow-Bellied Sliders are popular as pets.
Adult male yellow-bellied sliders typically reach 5–9 inches (13–23 cm) in length; females range from 8–13 inches (20–33 cm). The carapace (upper shell) is typically brown and black, often with yellow stripes. The skin is olive green with prominent patches of yellow down the neck and legs. As the name implies, the plastron (bottom shell) is mostly yellow with black spots along the edges. Adults tend to grow darker as they age. Yellow-bellied sliders are often confused with eastern river cooters, who also have yellow stripes on the neck and yellow undersides, but the latter lack the green spots characteristic of this species. The yellow belly often has an “s”-shaped yellow stripe on its face. They also have markings shaped like question marks on their bellie
Baby yellow-bellied sliders may be kept in a fairly small tank (20 to 40 gallons), but as they age, after about three years, they will require much more space. One Adult may be housed in a 75 US gal (284 l) (or larger) aquarium. The turtles require enough water to turn around, with a depth of 16–18 in (41–46 cm) recommended. Water temperature should be kept between 72–80 °F (22–27 °C) and properly filtered. Keeping fish with turtles is usually avoided due to the risk that the turtle will eat the fish. Sliders need a basking area that is kept warm during the day and that will allow the turtle to move around, balance, and dry off completely. This area should average 89–95 °F (32–35 °C) and can be heated with a UV-A heat lamp. A second lamp that produces UV-B is absolutely essential for the turtle to metabolize calcium properly. Direct, unfiltered sunlight is preferable. The lamps should be switched on during daylight hours.
