Your Guide to Aquatic Turtles

1. Red-Eared Slider (Trachemys scripta elegans)

Red-eared sliders are one of the most popular aquatic turtle species, known for their distinct red marks behind the eyes. These turtles are native to the southern United States and can grow up to 12 inches in length.

  • Habitat: Red-eared sliders need both land and water areas. A large tank (at least 40 gallons for one turtle) with a basking platform is essential.
  • Water Temperature: Maintain water temperatures between 75-85°F using an aquarium heater.
  • Diet: Feed them a balanced diet of commercial turtle pellets, vegetables (such as leafy greens), and protein (like insects or fish).

Red-eared sliders are active, curious, and easy to find in pet stores, making them a popular choice for beginners. They can live for 20 years or more, providing long-term companionship.


2. Eastern Box Turtle (Terrapene carolina carolina)

Although they are terrestrial turtles, Eastern box turtles are often kept as pets due to their manageable size (4-6 inches) and fascinating behavior. However, they require a slightly different care setup compared to fully aquatic species.

  • Habitat: While they spend time in water, Eastern box turtles need a spacious enclosure with a mix of land and water areas. A moist, humid environment with a shallow water source is ideal.
  • Water Temperature: Keep the water between 70-80°F, but ensure they have plenty of dry land for basking and foraging.
  • Diet: These turtles are omnivorous, eating a combination of fruits, vegetables, and animal proteins like insects and worms.

Eastern box turtles are known for their charming, interactive nature and can live for several decades with proper care.


3. Map Turtles (Graptemys spp.)


Map turtles, named for the intricate, map-like patterns on their shells, are native to North America. These turtles can grow up to 10-12 inches in length and are mostly aquatic.

  • Habitat: Map turtles need a large aquarium with a basking spot and clean, well-filtered water.
  • Water Temperature: Water temperatures should be maintained between 75-80°F.
  • Diet: They are omnivores, eating aquatic plants, small fish, and invertebrates.

Map turtles are hardy and relatively low-maintenance, though they are often a bit more shy than other species, making them ideal for quieter households.


4. Musk Turtles (Sternotherus spp.)


Musk turtles are small, semi-aquatic turtles that are known for their ability to produce a musky odor when threatened. They typically grow up to 4-5 inches and are great for smaller tank setups.

  • Habitat: These turtles prefer slow-moving water and need a well-structured tank with both aquatic and dry areas. A 20-gallon tank is suitable for a single turtle.
  • Water Temperature: Keep the water temperature between 75-80°F.
  • Diet: Musk turtles are primarily carnivorous and enjoy small fish, worms, and aquatic invertebrates.

Musk turtles are small and relatively easy to care for, making them perfect for beginner turtle owners with limited space.


5. Yellow-Bellied Slider (Trachemys scripta scripta)


Yellow-bellied sliders are a close relative of the red-eared slider, known for their striking yellow markings on their bellies. These turtles are also native to the southeastern United States.

  • Habitat: A large tank with a basking area and clean, filtered water is essential.
  • Water Temperature: Keep the water temperature between 75-80°F.
  • Diet: They are omnivores, eating a variety of vegetables, fruits, and protein such as fish and insects.

Yellow-bellied sliders are active and friendly, making them a great choice for families. With the right care, they can live for decades.


6. Chinese Pond Turtle (Chinemys reevesi)


Chinese pond turtles are native to China and are known for their attractive markings and peaceful demeanor. They can grow up to 8-10 inches and are relatively low-maintenance.

  • Habitat: These turtles need an aquarium with both water and land areas. A 30-gallon tank is suitable for one turtle.
  • Water Temperature: Keep the water between 75-80°F.
  • Diet: They eat a varied diet of leafy greens, fruits, and small aquatic animals like worms, snails, and fish.

Chinese pond turtles are friendly and easy to handle, making them perfect for first-time turtle owners. They are also more docile than some other species, making them ideal for children.


Aquatic turtles are a rewarding pet choice for those who are willing to meet their specific care needs. Whether you're interested in the active Red-Eared Slider or the more peaceful Chinese Pond Turtle, each species has its own unique requirements.

Before bringing a turtle home, be sure to do further research or consult with a veterinarian to create the best habitat and care plan for your new pet. With the right care, your aquatic turtle will be a fascinating and rewarding companion for many years.
