the most important thing to get for your turtle aside from food, water, ect. is a UVB light. turtles CAN'T live without it. you can use it in conjunction with a regular 60Watt light bulb. make both about a foot away from the tank, and make sure they are over rocks. But keep in mind the turts should have an area with no heat so they can cool off. Second, you need about a 30 gallon tank. what i use for my painted turtles hatchlings is a LONG & WIDE rubbermaid bin. Depending on whether you have babies or adults the height will vary. for babies it doesn't have to be very tall but adults can CLIMB WELL. be sure the walls a high for adults. aside from all this info, turtles are not just a project, if they are adults, I'd let them go in a nearby pond or lake, if they are babies, they are still able to be tamed. Just remember, Vet bills are going to be usually close to $100. Honestly, I think you should go onto
www.ask.com It's a website that answeres any question. just type in, "how do i care for a turtle?" But the best thing to do is to probably let them go. Eventually she's going to get bored of them, and also, throughout all expenses leading to pricing, you'll be paying easily over $150 to care for these. Unless you want to be taking care of these when you're little girls in collage, think otherwise. The populations declining for painters, you should let them go. Just think if someone took you out of your home? Your girl may not understand now, but she will later on. Hope this helps!!!!
