Health & WellnessMy turtle's shell looks split. Is her tank too small? Does she need UVB?
That hinge on her plastron (bottom shell) is normal. It is supposed to appear "split". That allows her to close up securely when she retracts her head.
These turtles do not get as big as other species, but a 10 gallon tank is too small. She also needs a UVB light source. Windows will block most of the sun's beneficial rays. You can find a UVB light source in most pet stores. A popular brand is the ZooMed ReptiSun light.
They are good eaters, eating a wide variety of animal protein, plant matter and commercial diets.
