Habitat, Tank Conditions & Settings

Some varieties of Skink are smaller, but most will require a larger tank at least four feet long, two feet wide, and at least one foot deep to give your reptile enough room to move. Also, it will need a screened top, so it doesn’t come loose, and the front opening will help you access the reptile. You can use glass or wood, as both will work well.

You will need to use a heating lamp to increase the temperature in your terrarium to over 70 degrees. We recommend brands that will provide your pet with essential UVB rays, which will provide your pet with the essential nutrients it normally gets from the sun. However, you’ll need to change your bulb frequently because it stops producing UVB rays long before it goes out.


As we mentioned earlier, you need to keep the temperature in your terrarium between 70 – 80 degrees. A heating lamp is a great way to increase the temperature, and it also provides a basking area that your pet will enjoy.


Humidity should remain between 40% and 60%. It should stay on the higher side when removing the skin. It also helps keep your Skink hydrated. A regular spray bottle will help you control the humidity level. Using a spray bottle to mist the reptile every few hours while keeping an eye on the ergometer will give the best results.

The substrate you use will depend on the type of Skink you have. For example, Desert Sinks will want a dryer, more sandy substrate, whereas those from wetter areas will do better with mulch. Most Lizards like to dig, so you should make sure the substrate is a few inches thick.

Keeping Your Blue Tongue Skink Healthy

Blue Tongue Lizards are relatively easy to maintain health as long as the habitat is large enough and the temperature and humidity are right. Lower humidity can cause the skin to stick and be difficult to remove, especially around the eyes.

General Health Problems

Parasites are a common problem for Blue Tongued Skinks. Usually get the parasites by eating foods that contain them. Wild-caught food is the easiest way to accidentally pass parasites on to your pet, and we recommend captive-bred food whenever possible.

Metabolic Bone Disease

Another big problem for many captive reptiles, including the Blue Tongue Lizard, is Metabolic Bone Disease (MBD). MBD occurs when your reptile doesn’t get enough calcium in its diet. This can cause your pet’s bones to become soft and brittle and may even cause your pet to be unable to move. Cleaning up insects and other food that you serve to your pet with calcium and Vitamin D3 supplements will help prevent the onset of this disease.

You can expect your Blue Tongue Lizard to live between 15 and 18 years if you are able to maintain the right habitat. These reptiles are quite hardy and have few health problems as long as you provide plenty of calcium.


Breeding the Blue Tongued Skink is as easy as placing a male and female in a terrarium during the spring. Mating rituals can seem cruel, and males can claw and bite females to help them gain position. However, if you feel there is a possibility of injury, it is best to separate it and try again with a different partner. If mating occurs and you see the female getting bigger within a few weeks, breeding was successful, and she will give birth to live babies.
