Species description

Geographical Origin and Habitat: Native to the mountain rainforests of Southeast Asia, primarily Cambodia and Vietnam. Prefers lower tree trunks and dense branches.

Taxonomy and Genetics: Member of the Agamidae family. The genus Acanthosaura is characterized by its head horns and spiked crests.

Behavior and Habits: Strictly arboreal and diurnal. Employs a sit-and-wait hunting strategy, staying motionless on tree bark for hours until prey approaches.

Morphology: Features long occipital spines and a distinct crest. Coloration ranges from green to brown. Males show larger throat pouches and brighter yellow tones.

Care, breeding and tankmates

Terrarium Setup: Requires a tall enclosure (at least 36 inches high) with stout climbing branches, cork tubes, and dense broad-leafed foliage.

Lighting and Heating: Keep daytime temperatures around 24-28°C with a basking spot of 32°C. Provide a high-quality UVB light source.

Humidity and Hydration: Maintain humidity between 60-80%. Spray daily or install a drip system, as they rarely drink from standing water bowls.

Feeding and Supplementation: Insectivorous. Feed live gutloaded crickets, roaches, and silkworms. Dust prey with calcium and D3 supplements.

Compatibility: Territorial. Best housed individually to prevent stress. Do not house multiple males in the same enclosure.

Health and Common Diseases: Vulnerable to internal parasites (especially wild-caught animals) and heat stroke if temperature gradients are too hot.
