Feeding the turtle Feeding Your Turtle 1. Do not overfeed your turtles. It will make a mess of your tank and the turtles may grow too fast, this puts them in danger of cracking their shells. Remember, to feed your turtle vegetables and fruit. Feel free to experiment with what your turtle likes.
Vegetables are especially good for older turtles.
Be careful when feeding live food that it is not to big for the turtle to eat. Also, make sure that it doesn't crawl out of the tank and escape. Be prepared for floating body parts. Don't feed your turtles anything you wouldn't eat yourself, excluding stuff like bugs, earthworms, and goldfish of course. It is best to stick to a natural diet.
