Turtles feed predominantly on plants. However, animal proteins in the form of insects and fish should also be regularly on the menu. With a one-sided and unbalanced diet, the animals are quickly prone to deficiency symptoms. These are often noticeable in the form of shell deformation or can lead to organ damage. Turtle feed should therefore contain an appropriate mixture of plants and animal proteins. In addition, you can equip the terrarium with water lettuce or floating aquatic plants. Even though they are so unassuming, turtles are also good hunters. In addition to turtle feed, there are also a few water fleas, amphipods or mosquito larvae that you can place in the terrarium.
