The Red-Eared Slider (Trachemys scripta elegans) is the most commonly kept pet turtle in the world — and the most commonly surrendered. Sold as cute hatchlings for $20, the species grows to 25–30 cm, lives 30+ years, requires a massive heated filtered aquarium, and is invasive in many countries when released.
Native to the south-central United States. Semi-aquatic — lives in ponds and slow rivers, basking heavily.
Now considered one of the world's worst invasive species. Banned for import to the EU (since 1997) and many Asian countries.
Adults 20–30 cm shell length (females larger than males), 1–2 kg.
Green to olive shell with red stripe behind each eye (the "red ear").
Active swimmers; not handling pets. Will bite if mishandled. Better observed than touched.
Adult minimum: 380 L (100 gallon) aquarium or larger. Many keepers use stock tanks or outdoor ponds for adults.
Provide:
Aquatic — humidity not separately managed.
Omnivore, shifting with age. Juveniles more carnivorous; adults more herbivorous.
20–40 years.
Common concerns:
Pros:
Cons:
Not suited for apartment dwellers without space, anyone planning short-term ownership, households with very young children (Salmonella).
Why are they considered invasive? Released or escaped pets establish in wild ponds, outcompeting native species. Banned from import in EU and many other regions.
How big do they get? Adult females reach 25–30 cm shell length. Males slightly smaller.
How long do they live? 20–40 years; some over 50.
Are they good for kids? Older children with adult supervision. The Salmonella risk and long lifespan make young-child ownership inadvisable.
Can I let them go in a pond? Never. Releasing pet turtles is illegal in most places and ecologically damaging.

"Red-eared sliders are sold as palm-sized babies. They grow to dinner-plate size. They live 30–40 years. They need 300+ litres of water. They are illegal as pets in the EU. They are the most abandoned aquatic turtle in the world. Today: the unvarnished picture before any purchase."
"Red-eared sliders (Trachemys scripta elegans) are native to the southern United States and northern Mexico. CITES regulated. Illegal to keep as pet in EU (Invasive Alien Species regulation). Established feral populations on multiple continents have caused ecological damage. Check law before purchase — confiscation possible."
"Tank minimum for one adult: 300 litres. Larger preferred — 450+ litres ideal. Filtration: powerful external canister rated 2× tank volume per hour. Basking area: dry platform with overhead heat lamp and UVB. Basking temperature: 32–35°C. Water 24–27°C. UVB: high-output T5 essential. Substrate: bare bottom or large smooth river stones. Decorations: hides and underwater plants."
"Juveniles: 50/50 animal/plant — pellets, fish, insects plus leafy greens. Adults: 30/70 animal/plant — primarily leafy greens, occasional pellets and fish. Calcium supplementation. Cuttlebone in tank. Never: dairy, bread, dog food."
"Many keepers move adult sliders to outdoor ponds — easier than maintaining huge indoor tanks. Pond minimum: 2000+ litres, secure walls, predator protection. Sliders tolerate UK and northern European summers but need indoor housing or hibernation arrangements in winter."
"Lifespan 30–40 years. Shell rot from poor water quality. Respiratory infection from cold drafts. Metabolic bone disease without UVB. Salmonella — turtles carry it; wash hands always. Find an exotics vet experienced with chelonians."
"Mistake one: small tanks. Stunts growth, causes shell deformities. How to avoid: 300 litres minimum from purchase. Mistake two: ignoring legality. EU possession can mean confiscation. How to avoid: confirm law before purchase. Mistake three: skipping UVB. Causes MBD. How to avoid: high-output T5 from day one."
"Checklist: Legal where you live. 300+ litre tank or large pond. Powerful filtration and UVB. Exotics vet identified. 30-40 year commitment with succession. Tick five — the slider can be a wonderful pet. Otherwise — please reconsider. Most sliders are abandoned within a year."
