Blue-tongued skinks love fruits and berries and it is perfectly safe to feed blueberry, blackberry, strawberry, raspberry and wild berries to your pet skink.
Berries in general are surprisingly low in sugar so you do not need to worry about feeding them regularly (unlike other types of fruits), although you may want to go easy on raspberries and strawberries in moderation because of some of their nutrients.

What berries can you feed to your skink
Strawberries
Blue tongue skinks can eat strawberries in moderation. Strawberries are healthy and nutritious – but they contain potentially harmful amounts of oxalates and goitrogens so they should not be a staple in your skink’s diet. A cup of strawberries contains almost 8 milligrams of oxalates.
Raspberries
Raspberries are surprisingly high in oxalates, with a whopping 48mg per cup. They are however a small fruit so it’s generally okay to feed them to blue tongue skinks as a treat, but they should not be a staple in your pet’s diet.
Blueberries
Blueberries are a healthy fruit option for your blue-tongued skink, plus they match the color of its tongue (cute). They only contain about 4 milligrams of oxalates per cup so they can be fed more regularly compared to strawberries.
Blackberries
Blackberries also contain only 4 milligrams of oxalates per cup which makes them another healthy food choice for blue tongue skinks.
