Red Belly Turtles are mainly herbivores that like to spend their time basking, so it’s really important that you give them a nice spot to bask in. They do well with some other turtle species, and you can even find them hanging out with Peninsula Cooters in their natural habitats because they are closely related. Red Bellies are great swimmers, too, so it’s a good idea to provide them with deep waters. They are herbivores and do really well with some of the turtle foods that we offer. Take a look at our selection and let us know if you have any questions about the Red Bellies. Again, they are an aggressive basking species so make sure you browse through the supplies on MyTurtleStore.com to find the right amenities for your turtle habitat! Red Bellies are very personable and any shyness will go away with a little care and attention. Size: Currently our Red Belly Turtles are 2 to 3 inches in size.
