I bred them for a few years till I figured out I could not compete with the WC Import Market. Most of those MHDs are wc
het for dead so be sure you are getting CB from the start. A good clue is if the horns are missing they are likely WC and will need a vet ASAP.
Here is the care sheet I used to hand out with my babies hope it is helpful.
Mountain Horned Dragon Care Sheet
Mountain Horned Dragons also called Mountain Horned Lizards are perhaps one of the most docile personable lizards in the pet trade today. Most specimens sold are wild caught yet do not respond with great signs of defensive aggression like most lizards. Due to the fact that they are wild caught a new MHD owner would do well to have their lizard examined by a vet, as soon as possible after receiving it, for a thorough examination and worming.
In the wild these water loving arboreal lizards live in the branches of dense jungle growth usually near a trickling stream.
Housing
A thirty gallon high aquarium (24 ¼ wide x 12 ½ deep x 24 ¾ high) should be considered the smallest acceptable enclosure for a young Mountain Horned Dragon. For one adult a tall custom built enclosure 36 inches wide X 18 inches deep X 48 inches high should be considered a minimum size.
The best setup for a Mountain Horned reflects their natural a shady rainforest home. They need thick vertical branches for climbing with plenty of plant cover to hide in. A stream or small waterfall with flowing filtered water will go a long way toward making them feel at home.
Lighting
There is some disagreement on the exact lighting requirements for the MHD some say that
UVB and Basking lights are not needed because the Mountain Horned lives in shady jungle setting where they get no sun. Others argue that the sun still shines down through the canopy to create basking spots where these lizards lay and absorb the
UVB rays that provide the vitamin D3 necessary for calcium absorption. I am inclined to agree with the latter as breeders of Mountain Horned Dragons have witnessed spinal and tail deformities in lizards not exposed to
UVB lighting as well as digestion problems when Basking lights were not provided.
UVB & Basking lights should be provided for 12 - 14 hours per day. The use of a timer will help to assure that the correct number of hours of light are provided on a set routine schedule.
Temperature
The ambient enclosure temperature for Mountain Horned Dragons should range between 70F & 75F. A basking light should be used to create a basking spot on a branch with temperatures between 80F to 85F. Night time temperatures may be allowed to drop to between 65F & 70F.
Humidity
As the MHD come from a humid jungle environment humidity should be kept at 70-80%.
Water and humidity are extremely important; a Mountain Horned Dragon can quickly become dehydrated if proper moisture is not provided. To maintain the proper humidity you can mist the enclosure once or twice each day. Another method that can be used to help maintain proper humidity is to place an aquarium air stone in their pond/water supply. The bubbles rising from the water increases the evaporation rate which helps to maintain a higher humidity in the enclosure.
Food
Horned Dragons are insectivorous and should be fed daily with calcium dusted silkworms, earth worms, crickets, roaches, Mealworm, Wax Worms, and with the silkworms and earth worms being their favorites.
Here is an approximate break down of prey items that can be fed to Mountain Horned Dragons;
Silkworms - Protein 54% / Fat 43% / Calcium 0.5% / Phosphorus 0.6% / Chitin (exoskeleton) low amount (This is the best feeder insect to use when available)
Earthworms - Protein 10.39% / Fat 7.2% / Calcium 1.18% / Phosphorus .9% / Chitin (exoskeleton) low amount (Though somewhat low in protein these have the best Calcium/Phosphorus Ratio of the feeder insects if you can get your lizard to eat them)
Crickets - Protein 50% / Fat 44% / Calcium 0.2% / Phosphorus 2.6% / Chitin (exoskeleton) medium amount (These MUST be gut loaded for 24 hours before feeding to your animal for proper nutrition)
Mealworms - Protein 37% / Fat 60% / Calcium
0.1% / Phosphorus 1.2% / Chitin (exoskeleton) high amount (I recommend feeding only very small and
freshly molted due to the possibility of intestinal impaction in small or young animals)
House Fly Larvae (yes maggots) – Protein 56.5% / Fat 17.2% / Calcium .37% / Phosphorous 1.13% / Chitin (exoskeleton) low amount (Though these have the highest protein percentage of any of these listed feeder insects they have a lousy Calcium/Phosphorus ratio)
Wax Worms - Protein 27% / Fat 73% / Calcium
0.1% / Phosphorus 0.9% / Chitin (exoskeleton) (Feed as treats only due to the high fat content)
Insects should be dusted with a good quality vitamin supplement once each week and calcium supplement at every feeding.
Water
As Mountain Horned Dragons love water and will spend many happy hours in it they should be provided with a water source that is large enough for them to swim & soak in. Since they do not like to drink from still, not moving, water you should at the very least place an aquarium air stone in their water so as to simulate moving water and stimulate drinking.
A far better idea, the one I use for our MHDs, is to install a stream and water fall system where the water is cycled from the swimming area into a filtration system then is pumped back into the stream where it flows back down to a small water fall and into the pond.
