When it comes to feeding juvenile blue tongue skinks, you have several options before you.

Here are some vet-recommended feeding options for juvenile blue tongue skinks:

  • Crickets, snails, mealworms, and waxworms are all good choices for feeding your juvie skink.
  • Pinky mice are also a good option but please limit feeding since they are high in fat.
  • Commercial reptile food like Zoo Med Blue Tongue Skink and Tegu food is also a great choice. Follow the feeding instructions on the label.
  • Chopped fruits and vegetables like dark leafy greens, carrots, apples, bananas, pears, dandelions, milk thistle, pawpaw, alfalfa, green beans, watercress, etc. are all excellent food choices for juvie blue tongue skinks.
  • Add a calcium supplement to your pet’s diet once a week.

Should You Buy A Juvenile Blue Tongue Skink for Pet? Pros and Cons Keeping Juvie Skinks as Pets

Should You Buy A Juvenile Blue Tongue Skink For A Pet? 

There are two lines of thought here.

Some experts believe that it is better to buy a juvenile blue tongue skink compared to a baby or an adult. This is due to the following reasons:

  • Baby skinks get to learn many things from their parents and siblings and should not be separated from them early on.
  • Juvenile skinks make better pets than adult skinks since they do not have rigid dietary preferences. They are more flexible or adaptable and also open to being handled and tamed. 
  • Juvies also need a lot less space compared to adult skinks which grow to almost 500 mm or about 20 inches. Adult skinks may even have poor breeding history and could develop health issues. They definitely need a lot more space compared to juvenile skinks.
  • The downside of keeping juvenile skinks as pets is that they need a lot more feeding compared to adult skinks. They also grow rapidly. Many beginners to skink husbandry tend to find juvenile skinks difficult to tame.

Others believe that baby skinks make better pets due to the following reasons:

  • Wild-bred mother skinks rarely care for their babies and abandon them soon after birth. Even captive-born and bred skink babies are usually separated by breeders after they are about 2 months of age. This is because, after this age, baby skinks start getting territorial and tend to fight with their siblings and parents for food, resources, etc.
  • There are some risks of keeping baby skinks with their moms as mommy skinks could accidentally kill their babies. You can read more about such incidents here.
  • This is why, breeders are willing to sell 2-month baby skinks. Usually, they do not sell baby skinks that are less than 2 months of age.
