Water turtles need an appropriately sized tank with water to swim and eat in, a basking area, floating food (including turtle pellets, leafy greens and chopped vegetables), cool and warm zones in their habitat (heated with incandescent bulbs or ceramic heat emitters and submersible heaters and monitored with several thermometers), UV light and calcium and multivitamin supplements. Their tank must be spot cleaned daily, have partial water changes weekly and be cleaned thoroughly every 2–3 weeks. Tank size must be increased as your turtle grows.
