Red-Eared Slider Care Sheet 

Red-eared sliders (Trachemys scripta elegans) are semi-aquatic turtles that can grow up to 30 cm in shell length and live for 20–40 years with proper care. They require a well-maintained aquatic and basking environment to stay healthy.

1. Habitat & Tank Setup

Tank Size

  • Juveniles (under 10 cm): Minimum 100L tank.

  • Adults (30 cm): Minimum 300L, though larger is better.

  • A secure lid is recommended to prevent escapes.

Water Conditions

  • Temperature: 22–26°C (juveniles may need slightly warmer water, around 26°C).

  • Filtration: Use a high-quality canister filter to handle waste, as turtles are messy.

  • Water Depth: Should be deep enough for swimming but allow access to a basking area.

  • Dechlorinate water before adding it to the tank (use Seachem Prime or similar).

Basking Area

  • Provide a dry, stable basking platform with easy access from the water.

  • Basking temperature: 30–35°C (use a heat lamp).

  • UVB Lighting: Essential for shell health and calcium absorption. Use a 10.0 UVB bulb and replace it every 6–12 months.

2. Diet & Feeding

Red-eared sliders are omnivores, but their diet should shift as they age:

  • Juveniles (more protein-based diet): 50-70% protein, 30-50% plants.

  • Adults (more plant-based diet): 20-30% protein, 70-80% vegetables.

Recommended Foods

✔ Protein Sources:

  • Live or frozen bloodworms, earthworms, crickets, mealworms, feeder fish (occasional)

  • High-quality turtle pellets (like Hikari, Reptomin, or Mazuri)

✔ Vegetables & Plants:

  • Leafy greens (kale, dandelion, romaine lettuce)

  • Aquatic plants (duckweed, water lettuce)

  • Carrots, zucchini, bell peppers (finely chopped)

❌ Avoid: Processed human food, dairy, citrus fruits, and iceberg lettuce (low in nutrients).

Feeding Schedule:

  • Juveniles (under 1 year): Feed daily.

  • Adults (1+ year): Feed every other day.

  • Remove uneaten food to maintain water quality.

3. Handling & Interaction

  • Red-eared sliders are not social pets and do not enjoy handling.

  • Only handle when necessary (e.g., tank maintenance, health checks).

  • Always wash hands before and after handling, as turtles can carry Salmonella.

4. Common Health Issues

Signs of a Healthy Turtle:

✔ Active and alert
✔ Smooth, hard shell with no cracks or soft spots
✔ Clear eyes and nostrils, no excessive mucus
✔ Eating and basking regularly

Potential Problems & Causes:

❌ Shell Rot (soft spots, peeling, bad odor) – Poor water quality or lack of UVB.
❌ Swollen Eyes/Respiratory Infection (bubbling from nose, lethargy) – Lack of warmth or poor nutrition.
❌ Soft Shell (Metabolic Bone Disease) – Lack of calcium or UVB exposure.
❌ Algae Growth on Shell – Poor water filtration or infrequent cleaning.

If you notice these symptoms, consult a reptile vet in NZ.

5. Legal & Ethical Considerations in NZ

  • Red-eared sliders are classified as an invasive species in NZ. Importing, or releasing them into the wild is illegal.

  • If you can no longer care for your turtle, contact a reptile rescue or pet rehoming service. Never release them into local waterways, as they can harm native ecosystems.

6. Final Care Tips

✅ Keep water clean and warm with a strong filter.
✅ Provide a basking area with heat and UVB lighting.
✅ Offer a varied diet with protein and vegetables.
✅ Regularly check for signs of illness and seek vet care if needed.
✅ Ensure secure housing to prevent escapes.

With the right care, your red-eared slider will thrive for decades! 🐢💧
