Mt. Horned Dragon


Your rating: None Average: 5 (1 vote)


Traits & behavior

This means they eat mostly live insects.

This means they're active during the day and sleep at night.

Mountain horned dragons are healthiest and happiest living alone.

Things to remember

Always supervise children when they're interacting with your mountain horned dragon.

Mountain horned dragons come from a "mountain forest" environment, and need a cool, humid home.

Food safety
Remove uneaten insects from the habitat at the end of the day; do not allow to remain in habitat overnight.

Safety & cleanliness
Please remember that all pets may bite or scratch, and may transmit disease to humans. Keep your pet's home clean and wash your hands before and after handling your pet or cleaning his home. Infants, young children, pregnant women, people with compromised immune systems, and the infirm or elderly are at greater risk of infections and should use caution when in contact with the pet or its habitat. Consult your doctor for more information.


Crickets & worms
Mountain horned dragons eat live, "gut loaded" (feed the insects a special supplement so they have extra nutrients) crickets, mealworms, superworms or waxworms.

Feeding frequency & amount
Feed juveniles once a day; adults daily or every other day - offer an amount that can be consumed by the end of the day.

Calcium dust

"Dust" the insects with a calcium supplement twice a week - ask a PetSmart associate for details.

Provide a bowl large enough for full-body soaking; change water daily. Also mist the surfaces in the habitat several times a day to maintain humidity and provide drinking water.


Signs of a healthy mountain horned dragon:

  • Curious, active behavior
  • Clear, alert eyes
  • Sheds regularly during growth
  • Eats and drinks normally
  • Breathes easily
  • Well-formed droppings every 2-3 days

Things to watch for:

  • Runny droppings or red streaks in droppings for more than two days
  • Lethargic behavior
  • Eating or drinking less; weight loss
  • Swollen joints
  • Discharge from the eyes, nose or mouth
  • Shedding problems; discolored skin

If you notice any of the signs above, please consult an experienced Reptile Veterinarian as soon as possible.


Use a 40-gallon or larger, glass terrarium with a screen lid for proper ventilation.

Hiding place
Provide a natural or artificial wood or rock hiding area.

Add a live tree and/or plant (a ficus or pothos works well), plus plenty of artificial reptile branches to create climbing areas.

Keep the humidity level between 65-75%. A hygrometer (humidity gauge) will help you keep track.


  • Day - Maintain a daytime temperature between 75-85° F
  • Basking - Provide a basking spot lamp to create a localized basking area of 95-100° F
  • Night - Maintain a nighttime temperature between 65-75° F
  • Place a thermometer at each end of the home to monitor temperatures

Use a daytime UVA/UVB fluorescent bulb for approximately 12 hours of light per day to help your pet process calcium.

Line the terrarium floor with 2"-3" of mixed bark and coconut fiber bedding. Clean out waste weekly and change bedding at least once a month.
