* Make sure your turtle's water is at about 26 degrees CELSIUS/ 79 degrees FAHRENHEIT. * Make sure your turtle has an artificial UVA/B light or natural sunlight. * Make sure your turtle has a basking area out of the water heated by a Tungsten basking lamp. * In Winter, have a glass lid covering the basking area of your turtles enclosure.
