They should also have plenty of room to explore and swim around in their tank or pond.

How Long Do Red-Eared Sliders Live in Captivity?

In their natural habitat they can live up to 40 years but in captivity, they usually only live 15-20 years on average.

The key is making sure that you give your pet a suitable home with enough space to swim and bask, clean water frequently changed so it doesn’t become stagnant, an appropriate temperature range that mimics their natural environment (around 75°F), plenty of calcium for shell growth and UVB lighting for vitamin D production.
