ive put my painted turtle with my red ear turtle it wasnt a good idea one of my mange to make a rock fall down and it landed on my painted turtle head, he is fine now, in the end have now put them in there own tanks, when they were living with each other my red ear would eat all the food before the painted turtle could get any. i have now done more reading up about the painted turtle, they are shy turtles and live more warm temps of water and like to hide, i have plants and fish with my painted turtle.
