Can a red ear slider turtle live with a painted turtle in the same tank?

yes and no,
Red Eared slider are a fresh water turtle from the Ohio river valley, Box tutrles are land turtle that can swim. When keeping them in the same tank (depending on size of all) one will be out of it natural environment. being in the incorrect environment can cause one the turtle to become sick. Box turtle live in dry woody environmet and like to sit in shallow water, if the box turtle stay to wet it can develope fungis or bacteria infection Red-Eared love water and tend to stay 90% of the time in or around the edge (quick get away), plus water turtle can not swallow with out water, no eating for a dry water turtle I have both, and I have built an outdoor pond with a beach and lots of land, the box turtles sit in the water from time to time but love crawling around in the dry oak leaves while the Red-Eared sliders sit on a log branch in the water to sun
