Painted Turtle (Chrysemys picta) Care Guide

Care for a painted turtle: a spacious heated aquatic tank, a dry basking spot with UVB and heat, strong filtration, and a commitment that can span 40-plus years.

Overview

The painted turtle (Chrysemys picta) is the most widespread native turtle of North America, a semi-aquatic freshwater species with bright red and yellow markings on its shell and skin. It spends much of the day basking to thermoregulate and is active only within a fairly narrow body-temperature range, so heat and light are central to its care.

Natural Range & Size

The painted turtle ranges from southern Canada to northern Mexico and from the Atlantic to the Pacific, across eight Canadian provinces and 45 US states, with Eastern, Midland and Western subspecies. It favours relatively slow-moving fresh water with a soft bottom, basking sites and aquatic vegetation.

• Adult carapace: 13-25 cm (5-10 in); males are smaller than females.
• Lifespan: up to 40 years in captivity, more than 55 years in the wild.
• All ages bask for warmth, often alongside other turtle species.

Aquatic Setup & Filtration

Apply about 10 gallons of water per inch of shell length; a roomy tank with deep, clean water suits this active swimmer. Painted turtles foul water quickly, so a high-quality external canister filter is essential to control waste and harmful bacteria, alongside regular water changes.

Basking & UVB / Temperature

Painted turtles bask for hours on logs and rocks to reach an active internal temperature of about 17-23 C (63-73 F). Provide a dry basking spot where the shell can fully dry, a heat lamp, and UVB lighting to drive vitamin D3 synthesis and calcium absorption.

• Active body temperature: about 17-23 C (63-73 F).
• Basking surface temperature: about 88-92 F (31-33 C).
• Provide both UVA and UVB lighting over the basking area.

Diet

Painted turtles are omnivores, eating leaves, algae, fish, crustaceans, aquatic insects and carrion. Young turtles are primarily carnivorous and need more protein, while adults become more herbivorous with age. Offer a varied diet of greens and animal protein appropriate to the turtle's age.

Health & Longevity

Painted turtles are remarkably long-lived, so plan for decades of care. Without adequate UVB or a balanced diet they develop metabolic bone disease and shell deformities; poor water quality causes shell and skin infections. Practise strict hygiene because turtles can carry salmonella.

Common Mistakes

• Keeping in shallow or undersized water with no room to swim.
• No dry basking spot or no heat lamp to reach active temperatures.
• Skipping UVB lighting, leading to soft shell and bone disease.
• Taking a turtle from the wild without checking protection laws.
