So when keeping these guys we like to feed them a variety of different items. In captivity we feed them on fresh prawns, small fish like whitebait, insects like crickets. They are carnivorous so they do like to eat more meatier foods and if you just chop it up and place it into the water the turtles will smell it and come and eat it. A turtle like this we’d offer food every second to third day. The more you feed them, the quicker they grow. And there’s times of the year depending on the size of your turtle that you wouldn’t bother feeding them at all. So, during the cooler months if it’s a large turtle you can let them hibernate and they won’t eat for six months of the year. A little guy in a tank like this I’d recommend feed every second to third day. .
