Also known as: Slider, Trachemys scripta elegans

A long-lived aquatic turtle that needs far more space than most owners expect.

  • Active
  • Curious
  • Independent
  • Hardy
  • Solitary

The red-eared slider is one of the most common pet turtles, recognised by the red stripe behind each eye. They are active, curious and long-lived, but they grow to 20–30 cm and need large, well-filtered tanks with basking areas and UVB lighting. Many are abandoned because owners underestimate their needs.

Common health problems

This section describes conditions the breed is known to be predisposed to, so you know what to ask about. It is not veterinary advice and is not a diagnosis — always speak to a vet about your own animal.

  • Metabolic bone diseaseCaused by poor UVB or calcium.
  • Shell rotLinked to dirty water or lack of basking.
  • Respiratory infectionsCaused by cold water or drafts.
  • Vitamin A deficiencyCauses swollen eyes.
  • SalmonellaWash hands after handling.

Never release sliders into the wild.

Interesting facts

  • Named for the red stripe behind each eye.
  • Invasive in many countries due to released pets.
  • Can live over 40 years.

Diet & Feeding

Sliders are omnivores. Juveniles eat more protein; adults need mostly aquatic plants and leafy greens with a quality turtle pellet and occasional insects or fish. Feed adults every two to three days.

Water, Heat & Lighting

Water should be 24–27°C, with a basking spot of 30–35°C. UVB lighting is essential for shell and bone health. Replace UVB bulbs every 6–12 months.

Tank & Basking Setup

Adults need a tank of at least 300 litres, more for larger turtles, with powerful filtration and a dry basking platform. Water must be deep enough to swim and kept very clean.

Health & Vet Care

Watch for metabolic bone disease, shell rot, respiratory infections and vitamin A deficiency. Turtles can carry Salmonella — wash hands after handling.
