Can Bearded Dragons and Blue Tongue Skinks Live Together

Keeping a bearded dragon and blue tongue skink together is a bad idea, so the safe answer is no. The Merck Veterinary Manual says different species from different locations must not be mixed. Ideally only one species lives in any enclosure.

This guide covers the reasons, what contact would involve, and how to house each lizard alone. For the broader picture, see the guide to housing a bearded dragon with other species.

Which lizards are we talking about?

The bearded dragon here is Pogona vitticeps, the central bearded dragon. Animal Diversity Web calls it semiarboreal, found from desert to dry forest and scrubland in eastern and central Australia. Males use beard inflation, arm waving and head bobbing to signal dominance or courtship.

Blue tongue skinks are a genus, Tiliqua, and the species matter. The National Zoo describes the northern blue tongued skink (Tiliqua scincoides intermedia).

Animal Diversity Web describes the common blue tongued skink (Tiliqua scincoides). Each skink fact below names its species and is not a claim about the dragon.

Bearded dragon and blue tongue skink together: size and injury risk

Body size is the first practical problem. The northern blue tongue skink typically reaches 17 inches (45 cm), with a maximum of 22 inches, per the National Zoo. Animal Diversity Web lists an average of 33 cm and 493 g for Tiliqua scincoides.

Bearded dragons (P. vitticeps) measure 13 to 24 inches with the tail, so the two overlap in length.

The northern skink has small teeth that still deliver a painful bite, according to the National Zoo. When threatened it puffs up, gapes and hisses.

Merck notes that feeding injuries are common when reptiles share an enclosure. A bite to a dragon’s toes or tail is that kind of injury.

Predation and territorial stress

Animal Diversity Web lists the common skink as eating insects and other reptiles. It lists the bearded dragon as occasionally eating small lizards.

Neither is a dedicated lizard hunter, but both accept lizards as food. That is a poor basis for sharing a closed space with a juvenile dragon.

Even without attacks, competition causes harm. Merck names competition for food, basking sites and shelter as a source of stress and health problems.

A dragon chased off its basking spot cannot warm up to digest food. A skink that hides constantly may stop eating.

Different climate and lighting needs

LafeberVet reports that P. vitticeps needs UVB for calcium metabolism and does best across thermal zones of roughly 25 to 40 C.

Merck adds that UVB sources should sit close, under 30 cm, for diurnal lizards generally. A dragon’s enclosure is built around a hot, bright basking area with a wide gradient.

Skinks are not one uniform group. The northern subspecies lives from forest to grassland, and the common skink also occurs in New Guinea and Tasmania. That points to different climate needs than a desert dragon.

Merck states that humidity requirements vary by species. For the northern blue tongued skink, LafeberVet gives a cool end of 21 to 29 C, a basking spot of 33 to 38 C and humidity of about 30 percent.

Those numbers overlap with a dragon setup more than many keepers expect. The case against sharing does not rest on climate. It rests on what LafeberVet says next: the northern skink must be housed alone, because even juveniles will fight savagely.

A lizard that attacks its own kind will not treat a dragon as a friend. Other skink species and localities have their own needs, so ask a reptile veterinarian about the exact species you keep.

Diet mismatch

The northern skink is an omnivore eating insects, snails, carrion, fruit and leaves. The National Zoo feeds its skinks greens, vegetables, crickets and earthworms. A dragon has its own supplement schedule from LafeberVet: calcium without D3 two to three times a week, and a multivitamin two to three times a month.

Shared food dishes lead to the wrong animal eating the wrong meal. A dragon eating skink food, or the reverse, is a nutrition problem that develops slowly. Feeding them in separate rooms removes the guesswork.

Salmonella and parasite cross infection

The CDC states that even healthy reptiles carry Salmonella in the gut. A person can get sick without touching the animal, through tank water or equipment.

This applies to reptiles in general, not one species. Every reptile in a home is a possible source.

Merck describes mites under 1.5 mm that affect most reptiles worldwide. They can carry bacteria and viruses mechanically.

The chapter does not say mites move between skinks and lizards, so treat that as a risk, not a proven fact. Merck recommends screening and 3 to 6 months of quarantine for new reptiles.

Is supervised contact ever acceptable?

No source supports deliberate contact between these two species, and neither animal gains anything from it. If they meet by accident, separate them at once and check both for bites and torn skin.

Do not let either lizard roam freely in the home. The CDC advises keeping reptiles and equipment out of kitchens and anywhere food is prepared or eaten.

If you insist on a short side by side session, use these rules:

• Keep both animals on a clean, easily washed surface in a room without other pets.
• Stay within arm’s reach and end the session at the first hiss, gape, beard flare or chase.
• Never leave them together unattended, even for a minute.
• Never do this with a juvenile dragon.
• Wash your hands with soap and running water afterward, as the CDC advises.

What to do if they already share space

Separate them today and set up two complete enclosures before returning either animal. Weigh each lizard and photograph any wounds, then book a visit with a reptile veterinarian if either has bite marks, a lost toe or tail tip, or stops eating. Merck says new or exposed reptiles should be quarantined for 3 to 6 months, so treat the pair as exposed to each other and clean everything with soap and water.

Watch for stress signs afterward. These include hiding all day, refusing food, staying away from the basking area, and repeated gaping or beard flaring at nothing. A dragon that loses interest in food for more than a few days needs a veterinary check, because stress is only one of several possible causes.

How to keep both lizards safely

Give each lizard its own enclosure, in separate rooms if possible. Use dedicated tools, dishes and cleaning supplies for each tank, and never wash them in a kitchen sink. Clean enclosures with soap and water, since Merck warns that phenolic disinfectants are toxic to reptiles.

Handle one animal, wash your hands, then handle the other. The CDC says children under 5, adults over 65 and immunocompromised people face higher risk.

Children under 5 should not touch reptiles or their environments. Quarantine any new animal for 3 to 6 months, per Merck.

Other pairings, such as geckos, have their own pages.

The same rule applies to iguanas.

Frequently Asked Questions

Can bearded dragons and blue tongue lizards live together?

No, because Merck says different species should not be mixed. Size, defense and diet differences add to that. Keep each in its own setup.

Can you house a blue tongue skink and bearded dragon together if they grew up together?

Growing up together does not remove the risk. A bearded dragon and blue tongue skink together still face competition over basking sites and food still causes stress, according to Merck. Lifelong separate enclosures are the safer plan.

Can a bearded dragon live with a blue tongue skink in a very large enclosure?

Size does not fix the problem, because LafeberVet says the northern skink must be housed alone since even juveniles fight savagely. A big enclosure also makes it harder to watch for bites and missed meals. No source supports it, so a large setup is not a workaround.

What should I do if a skink bites my dragon?

Separate them, then rinse the wound gently and watch for swelling, discharge or refusal to eat. Book a visit with a reptile veterinarian for anything deeper than a scratch. Keep the animals apart from then on.

Can a skink give my bearded dragon a disease?

Reptiles in general carry Salmonella and can carry mites, per the CDC and Merck. No source confirms skink to dragon spread. The risk is unproven but still justifies separate housing and quarantine.

Do I need to wash my hands between handling the two?

Yes. The CDC advises soap and running water after handling animals, feed, feces or tank cleaning. Do it between animals too.
