What is a small red-eared slider bought from a pet shop like?

Small red-eared sliders from pet shops vary in quality, and you only learn by keeping one for a while. When choosing, check the limbs and tail for injuries and whether the legs push strongly, and see if the shell is smooth and round. Then flip it over to check it can right itself; if all is normal, its health is good and you can take it home.

After arrival, prepare a properly sized container with few decorations but a ramp and a small basking platform so it can climb up to sun and rest, plus a small hiding house to help it adapt faster.
