Nutrafin basix Floating Turtle Gammarus Pellets should be fed as a core diet. The easily digested floating food sticks are effortlessly consumed by turtles, helping to control their messy feeding habits. Turtles and terrapins should be fed a varied diet containing freeze-dried foods like Nutrafin basix Turtle Snack (freeze-dried Gammarus).
Been feeding my terrapin this for years together with Mazuri pellets and will keep buying. It's a very large bottle and the expiry date is in 2024 so it'll last a long time.
