Thanks for reaching out about Bob Luigi and including a photo. Males typically have two differences than females, but sometimes difficult to determine. Males tend to have very long front nails. Males also have longer, more narrow tails, where the females have shorter tails and the cloaca is at the edge of the shell. Good luck.

    Leonardo may be too young or too small to accurately determine gender. Wait until he/she is about 4 inches in length. Female sliders have a smaller, thinner tail and shorter front claws than males do. the cloaca, or vent, is located closer tot he body in female sliders.
