Red-Eared Slider Turtle Habitat Setup

Tank Size

A Red-Eared Slider Turtle needs a large tank. The rule of thumb is 10 gallons of water per inch of shell length. For an adult, a 75–100 gallon aquarium is ideal.

Water Quality

Since Red-Eared Sliders spend most of their time in water, filtration is crucial. A canister filter is recommended to maintain clean, toxin-free water. Perform 25–50% water changes weekly.

Basking Area

Provide a dry basking platform with a ramp so your turtle can easily climb out of the water.

Temperature & Lighting

• Basking area: 85–90°F (29–32°C)

• Water temperature: 75–80°F (24–27°C) for adults, slightly warmer for hatchlings

• UVB lighting: Essential for calcium absorption and shell health. Replace bulbs every 6–12 months.

Red-Eared Slider Turtle Diet

Red-Eared Slider Turtles are omnivores and need a varied diet to stay healthy.

Juveniles eat more protein, while adults shift toward plant-based foods.

Recommended Foods:

• Commercial turtle pellets (main diet)

• Leafy greens: romaine lettuce, collard greens, dandelion greens

• Vegetables: carrots, squash, zucchini

• Protein (occasionally): earthworms, crickets, mealworms, cooked fish

Avoid: iceberg lettuce, raw meat, bread, or processed foods.

Handling and Temperament

The Red-Eared Slider Turtle is not a cuddly pet. They prefer swimming and basking rather than being held. Over-handling can stress them and may lead to bites. However, they often recognize their owners and swim toward them during feeding time.

⚠️ Always wash your hands before and after handling turtles due to the risk of salmonella.

Common Problems:

• Shell Rot: Fungal/bacterial infection from poor water quality

• Respiratory Infections: Wheezing, swollen eyes, or tilted swimming

• Vitamin A Deficiency: Puffy eyes, poor appetite

• Metabolic Bone Disease: From lack of calcium and UVB lighting

Prevention:

• Keep water clean
