Raising a painted turtle (Chrysemys picta)âone of North Americaâs most colorful and popular native turtlesâcan be a rewarding long-term commitment. Known for their vibrant red, yellow, and olive shell markings, painted turtles are semi-aquatic, active, and relatively hardy when given proper care. Below is a complete, species-focused guide to raising a healthy painted turtle.
Size: 4â7 inches (10â18 cm), depending on subspecies (Eastern, Western, Midland, or Southern)
Lifespan: 20â40+ years in captivity
Temperament: Generally calm, curious, and good-natured
Habitat in wild: Shallow freshwater ponds, lakes, marshes, and slow-moving streams with abundant basking sites and vegetation
đ˘ Note: Painted turtles are protected in many statesânever take from the wild. Always choose captive-bred individuals from reputable breeders.
Tank Size (Indoor)
Hatchlings (under 4"): Minimum 20â30 gallons
Adults: 75â125 gallons (long-style tanks preferred)
Rule of thumb: 10 gallons of water per inch of shell length
Water depth: At least 1.5â2 times the turtleâs shell length (e.g., a 5" turtle needs 8â10" of water)
đ Outdoor ponds are excellent for adults in warm climates (USDA zones 6â10), but must be secure, predator-proof, and include basking areas and shade.
Water Quality
Use dechlorinated water (tap water treated with reptile-safe conditioner)
Install a high-quality canister filter (rated for 2â3x the tank volume)âpainted turtles are messy!
Perform 25â50% water changes weekly
Test water regularly for ammonia, nitrite, nitrate, and pH
Temperature
Water temperature:
Hatchlings: 78â80°F (25â27°C)
Adults: 75â78°F (24â26°C)
Basking area: 88â92°F (31â33°C)
Use a submersible heater (with guard) and a basking heat lamp
Lighting
UVB lighting is non-negotiableâprevents metabolic bone disease
Use a 5.0 or 6% linear UVB fluorescent tube (e.g., ZooMed ReptiSun 5.0 or Arcadia Forest 6%)
Replace every 6â12 months
Position within 10â12 inches of basking spot (no glass/plastic blocking UVB)
Photoperiod: 10â12 hours of light per day (use a timer)
Basking Platform
Must allow the turtle to fully dry off and stretch out
Options: Commercial docks, stacked smooth rocks, or floating platforms
Ensure itâs stable, slip-resistant, and easily accessible
Substrate & Enrichment (Optional)
Bare-bottom tanks are easiest to clean
If used: large, smooth river stones (too big to swallow)
Add hiding spots, driftwood, and live or silk aquatic plants (e.g., anacharis, java moss)
Painted turtles are omnivores, but their diet shifts with age:
Diet by Age
Juveniles (<2 years): 60â70% protein, 30â40% plant matter
Adults: 30â40% protein, 60â70% plant matter
Protein Sources
Earthworms, crickets, mealworms (occasionally), bloodworms, blackworms
Small fish (e.g., guppies, minnowsâavoid goldfish)
High-quality turtle pellets (e.g., Mazuri, ReptoMin)
Plant Matter
Duckweed, water lettuce, water hyacinth
Chopped kale, collard greens, dandelion greens, shredded carrots
Avoid iceberg lettuce (no nutritional value)
Feeding Schedule
Juveniles: Daily
Adults: Every other day
Always feed in waterâthey need it to swallow
Remove uneaten food after 15â20 minutes
Supplements
Calcium (without D3 if using UVB): 2â3 times/week
Multivitamin: Once weekly
Basking behavior: Essentialâwatch for regular basking; refusal may signal illness
Common health issues:
Soft shell (calcium/UVB deficiency)
Swollen eyes (vitamin A deficiency or poor water quality)
Shell rot (fungal/bacterial infection from dirty water)
Veterinary care: Annual check-ups with a reptile/exotic vet are recommended
Never release pet turtles into the wildâthey can spread disease or disrupt ecosystems
Housing multiple turtles: Possible, but monitor for aggression; provide extra space and basking areas
Legal status: Check local lawsâsome states prohibit owning native turtles without permits
With proper care, a painted turtle can be a vibrant, engaging pet for decades. Their beauty and active swimming make them a favorite among turtle keepersâjust remember theyâre a long-term commitment.
