what do I do if my baby turttle is not eating

How long have you had him he may be getting used to his enviroment. Also what kind of setup do you have and what kind of turtle do you have? Semi-aquatic turtles must be fed in the water. For more help come to http://www.turtleexchange.com/forum/inde. It's a great forum with great people!

Also read this:

* Is the turtle kept warm enough? If turtles get too cool, they will stop eating.

* Does the turtle like the food you offer? Try out different foods. Some turtles can be very finicky eaters, especially in the beginning. And they have definite likes and dislikes. Most turtles will eventually take small earthworms that are wiggling in front of their nose. Start feeding favorite foods, then slowly introduce other items.

* Is your turtle exposed to too much stress? This is often a cause in new animals. Stress can be caused by handling, traveling, tank mates. New turtles will often not eat properly for several weeks. Be patient and keep trying.

* Is your turtle healthy? Not eating can be a symptom of other problems. If your turtle has been eating well and suddenly stops, a health problem is a likely reason. Take a fecal sample to your veterinarian. (Fecal samples need to be no older than 4 hours, and you need to store them in water in the refrigerator.)

* Don't panic! A turtle can go without food for weeks, even months, and when it feels well again, it will eat again. See a veterinarian, if you think you are doing everything right, and the animal does not eat for more than 2 weeks.
