Blue Tongue Skink Care Sheet

Care sheet for the Northern blue tongue skink (Tiliqua scincoides intermedia).

This care sheet applies specifically to the Northern blue tongue skink but most species and sub-species

of blue tongue skinks can be kept using these guidelines.


Blue Tongue Skink Introduction
Northern blue tongue skinks inhabit the woodlands and grasslands of northern Australia. Blue tongue skinks are ideal for beginners with loads of personality and great dispositions. They are also an excellent choice for advanced hobbyists as breeding them can be challenging and certain species and localities are extremely rare.


Blue tongue skink Availability
Northern blue tongue skinks are available seasonally in the pet industry. Other species, including Indonesian blue tongue skinks (
Tiliqua gigas gigas), are more readily available, but Northern blue tongue skinks are hardier and make better pets. Be sure to choose reptiles from a reputable source and look for active lizards with bright, open eyes. Check for toes absent of unshed skin and observe the overall health of the lizard.


Northern blue tongue skinks range in price from $150-$250 for babies and adults. High colored or rare examples may be more. Rare blue tongue skinks such as Centralians and Shinglebacks will cost $1500-$5000 each.


Blue tongue skink Size
Northern blue tongue skink adults usually range 18-24 inches in total length and are the largest of the blue tongue skinks.  


Blue tongue skink Life Span
Kept properly, blue tongue skinks will easily live 15 to 20+ years.


Blue tongue skink Housing

Baby blue tongues should be housed in specialty plastic cages, terrariums or 10-20 gallon glass tanks with full screen tops. Babies should always be kept separately. Adult blue tongue skinks require an enclosure at least 36L x 18W x 10H with a full screen top. Blue tongues are terrestrial and prefer floor space over climbing area. Larger enclosures will be appreciated. Blue tongue skinks are best kept separately. You may be able to house females together, or a male and female pair, but observe any cage mates very closely. If they fight, then keep them in separate cages. Males should never be kept together.


Blue tongue skink Lighting and Temperature
Reptiles control their body temperature through thermoregulation. Every cage should have a warm side and a cool side. This is very important! Place all heating and lighting at one end of the cage (far left or far right). If your reptile gets too warm, he will move to the cool side. If he is too cool, he will move to the warm side. This is a simple definition of thermoregulation. All reptile cages should include a thermometer to monitor temperature.


Blue tongue skink enclosures should have temperatures on the cool side of 75-82F and the cool side can drop to 70F at night. The warm end of the enclosure should have a basking area of 90-100F. This can be accomplished with an under tank heater, an incandescent basking light (or heat emitter), or a combination. Overhead lamps are appreciated as they allow the skink to bask. All heating and lighting devices should be placed on the warm end of the enclosure. If an under tank heater is provided, overhead heating devices can be turned off at night. Daylight bulbs should be on a maximum of 12 hours each day.


Conflicting opinions about the blue tongue skinks need for full-spectrum lighting are held. There are several documented cases of blue tongues being raised successfully without any exposure to full-spectrum lighting. I do suggest UVB lighting in enclosures and UVB is generally recommended for keeping blue tongue skinks. UVB lights should be on 8-12 hours each day. Any UVB bulb will also provide UVA which is beneficial to blue tongue skinks.


Blue tongue skink Substrate and Accessories
Aspen, recycled paper substrates, fir bark, cypress mulch (not kept moist) and artificial turf (not preferred) can all be used. Whichever substrate is used, be sure the skink does not ingest it. Ingesting substrate can be deterred by using a feeding dish. Blue tongues spend their time on the ground so keep the substrate clean and maintained. NOTE: cedar chips, clay cat litter, orchid bark and walnut shells should never be used. These substrates may lead to toxicity, impaction or respiratory concerns.


Blue tongues may climb over rocks and logs but they are not good climbers so be sure they cannot fall from high ledges. Proper housing accessories include cork bark, Mopani wood, logs, large rocks and hide boxes or shelters. Do not clutter the cage as blue tongues enjoy plenty of open space. Any elaborate decorations will be rearranged by skinks.


Blue tongue skink Diet and Feeding
While blue tongues are extremely hearty animals that will thrive on just about any diet, a well-balanced diet will result in a more active, healthier skink. They are omnivorous and should be fed a combination of meats, vegetables and fruits. Variety is the most important aspect of their diet. Switch protein sources and use diversity when feeding canned foods. A balance of 50% vegetables/greens, 40% meats and 10% fruits is ideal. Adults should be fed every other day. Baby blue tongues do best when fed daily. Feed them as much as they will eat in one sitting. Obesity problems seen in other lizards are rarely seen in blue tongues. Uneaten food should be removed when the skink is finished.


A quality vitamin/calcium supplement with vitamin D3 may be important, especially if the diet is not varied and well-rounded. A sprinkle over the food every third feeding is sufficient for adults (every other meal for young blue tongues). Varying opinions occur about the need for this supplementation, but it is usually recommended.


Below is a list of menu items for your blue tongues. Feel free to try other possibilities but avoid citrus, avocado, eggplant, rhubarb and high sodium canned meats/foods.



         Canned super premium dog/cat food

         Dry super premium dog/cat food (moistened)

         Canned insect products (any variety, but snails are a favorite)

         Mealworms and Superworms

         Hard-boiled eggs

         Boiled chicken

         Ground turkey (cooked)

         Lean ground beef (cooked)

         Pinky Mice (live or frozen/thawed, but only occasionally)



         Collard Green

         Turnip Greens

         Mustard Greens

         Squash (including spaghetti, scallop, butternut, acorn, Hubbard, etc.)


         Brussel sprouts


         Dandelions (pesticide free)

         Hibiscus flowers (pesticide free)









Several brands of dog/cat food are available with good ingredients. If feeding canned dog/cat foods, be sure to feed only super premium foods with no by-products and no meat/bone meal. Many foods are also available with fruits and vegetables included, which is not a substitute for fresh foods, but is better than 100% protein foods. Cat foods usually contain twice the protein of dog foods. I suggest dog food diets for blue tongues over cat foods. If a skink appears thin or has just been rescued from improper conditions, cat/kitten food will help add weight. Cat food may also be fed to breeding skinks. Be sure to read the label on all foods and see the notes below.


Many reptile (and even dog/cat) foods on the market contain little or no nutrition, despite what they advertise with the false information on their packaging or television. See the guideline below for foods with little or no nutrition (don't believe their packaging). If they contain any or all of the ingredients listed below, they are a low quality food.


Below is a simple guideline for foods NOT to use:

         Corn based foods

         Foods containing artificial colors

         Foods containing by-products (i.e. chicken by-products)

         Foods containing meat/bone meal

         Water as main ingredient


Blue tongue skink Water and Humidity
Clean water should always be accessible in an appropriate water dish. Blue tongues are not good swimmers and must be able to easily exit the water bowl. Northern blue tongues are from semi-dry areas and require low humidity with adequate ventilation. Humidity levels ranging between 25-40% are ideal. A hygrometer (humidity gauge) can be used to monitor humidity levels. NOTE: Indonesian, Tanimbar, Irian Jaya, Merauke, and Kei Island blue tongue skinks may prefer slightly higher humidity in the 40-45% range.


Blue tongue skink Handling and Temperament
Any new reptile should be allowed to acclimate for a few days and should not be handled until he is comfortable in the new environment. Once the new reptile is feeding regularly, then handling can begin. First handling sessions should be ten minutes or less. Be sure to hold blue tongue close to the floor or on a bed in case he is dropped. Be sure to fully support the skinks entire body so he feels secure. Blue tongues are very personable and often enjoy a good scratch on the head or chin. Many reptiles do not like to be handled and some reptiles tolerate it. Blue tongue skinks seem to enjoy attention.


Blue tongue skink Final Words
Blue tongue skinks will consistently reward and surprise their keepers with their friendly and curious personalities. They are great for reptile enthusiasts of all levels. The unique and intelligent blue tongue skink may be the ultimate pet lizard.
