Red-eared sliders and other aquatic turtles are commonly kept as pets but require specific conditions including large water volumes, UV-B lighting, and basking areas that few owners provide.
Aquatic turtles are among the most commonly kept reptiles and among the most poorly cared for. They start as small, appealing hatchlings and grow into large animals with complex needs including strong UV-B lighting, precise temperature gradients, large clean water volumes, varied diet, and dry basking areas. Most pet turtles spend their lives in tanks too small, with insufficient filtration, no UV-B, and inadequate nutrition. The result is metabolic bone disease, shell deformities, and shortened lifespans — preventable harms that arise from the mismatch between low purchase price and high care costs.
