How to Care for a Red-Eared Slider (Brazilian Turtle)

1 Setting Up the Habitat

Red-eared sliders live in an aquarium or tub and are fairly tolerant, which is why many beginners choose them. But without the right care, they are still prone to illness and loss. The following covers the essentials of keeping one healthy.

Prepare a tank or tub large enough for the turtle to swim freely. At least one side should be transparent so the turtle can bask and observe its surroundings.

Keep the water in the turtle’s preferred range of 20 to 30 degrees Celsius, using an aquarium heater or heat lamp to hold the temperature steady.

Add a floating island or land area where the turtle can climb out to sunbathe and rest. If natural light is unavailable, use a suitable UVB lamp to mimic sunlight; this helps the turtle absorb calcium and supports healthy bone and shell growth.

Keep the water clean. With a filtration system you need not change it daily; replacing one half or one third of the water every two weeks is usually enough. Without filtration, increase the frequency based on water quality and how many turtles you keep, and keep the substrate tidy to avoid bacterial infection.

2 Feeding Your Turtle

Red-eared sliders are omnivorous. Their diet should combine vegetables, fruit, insects, and commercial pellets for balance, plus appropriate calcium and vitamin supplements to support health and bone development.

Aquatic plants: they enjoy duckweed, algae, and ferns, which supply fiber and vitamins important for digestion.

Vegetables: cabbage, carrot, broccoli, cucumber, and pumpkin are rich in vitamins and minerals and benefit the turtle.

Fruit: apples, grapes, pears, and strawberries are welcome treats, but offer them only in moderation because of their high sugar content.

Protein: earthworms, crickets, small fish, shrimp, bloodworms, and mealworms provide the protein and minerals essential for growth.

Choose a high-quality commercial turtle pellet that contains the vitamins and minerals a slider needs. Always feed clean, fresh food, avoid overfeeding and too much sugar, and watch appetite and digestion. If your turtle stops eating or shows digestive trouble, consult a veterinarian.
