Eastern Blue Tongue Lizard

Natural distribution: Occur throughout eastern and northern Australia where they occupy a wide variety of habitats ranging from temperate lowland grasslands,  dry sclerophyll forest,  semi-arid grassland and woodland,  and coastal plains.   

Adult size (including tail): 450-600mm

Temperature in captivity:  Day time air temperature 23-26°C,  night time should not be lower than 18°C.The Blue-tongue should be able to regulate its body temperature in a basking spot (range of 30-40°C) on the floor of the vivarium.  Reptile One Daylight Basking Lamp or Reptile One Fan Heater positioned over the selected basking spot is ideal;  the soft air movement created by the Reptile One Fan Heater circulates the air in the vivarium more efficiently.  The wattage size of the lamps are determined by the size of the vivarium and internal décor.

Eastern Blue-tongues are diurnal (day time) reptiles and will require the day lights/ heat lamps to be turned off at night.  To keep your Blue-tongue  warm at night,  place a Reptile One Heat Mat under a Reptile One Cave or Log,  this will allow the Blue-tongue to settle on the mat while feeling protected by the ornament.  The Reptile One Heat Mat can be left all the time so do not position directly under the Reptile Daylight Basking Lamp.  The heat mat should not greater than 25% of the floor area.

Lighting: Reptile One Fluorescent Reflector with a Reptile One UVB5.O tube positioned 30cm above the basking spot,  will provide useful UV to enhance dietary calcium absorption and vitamin D3 production essential to Blue-tongues.

Enclosure: Reptile One have a range of enclosures and cabinets that are suitable for Blue-tongues,  minimum suggested size for juveniles would be 60cm and adults 90cm with a choice of glass or timber finishes.

The aesthetic properties of the Reptile One Bedding for Lizards will provide an ideal substrate and allow for ease of cleaning up after your Blue-tongue.  Your Blue-tongue will benefit from the inclusion of artificial plants to provide shade areas in the vivarium similar to the lizard’s normal environment.  

Ornaments: A choice of Reptile One decorative rocks and tree branches will give you the ability to provide natural retreats.

Diet & Feeding: Blue-tongues are basically omnivorous,  requiring a balance of Insects (crickets,  cockroaches, mealworms),  snails,  slugs or earthworms and a mix  of green and red vegetables (spinach,  coloured lettuce,  tomato, red or green peppers,  mushrooms or rose petals) and raw eggs.  Occasionally some boiled egg can be added to the mix, fruits will also be taken with relish,  some Blue-tongues will develop preferences so try a range of fruits like;  apple, banana, pear,  fig ,melon,  plum,  kiwi fruit,  raisins or strawberries,  depending on what is in season.Food is best offered to Blue-tongues in the late morning through to midday,  after they have had time to bask and have become active.  Food can be left in the enclosure until the Blue-tongue has finished eating,  it is best to remove leftovers as soon as possible that day.

Blue-tongues will prefer their food presented in a shallow bowl.  It is suggested to feed juvenile Blue-tongues 5 times per week while adults can be fed 3 times per week.Water dishes should be stable and replenished daily.

Handling: It is recommended before purchasing your Blue-tongue to have a demonstration on the best way to hold juvenile and adult Blue-tongues.


Seek advice from a reptile specialist veterinarian for all health issues.

It is illegal to remove Blue-tongues from the wild in Australia without the appropriate Government permits,  please check your states regulations on the appropriate permits to enable you to keep captive bred Blue-tongues.  Please do not release any captive Blue-tongues into the wild as this will disrupt the natural order of our environment.
