Its a four year old Map Turtle that I got from someone who didn't want it anymore. I doubt the lack of eating is down to settling in as he'll eat mealworms but won't touch the turtle food, fish, shrimp or any fruits I give it. The turtle food I have is the same as its previous owner used. I know that mealworms can't be used as a staple diet so I need to know what to do about it.
