1 Overview

The fire crest lizard is a typical arboreal lizard, mainly inhabiting forests near waterways. It is also a typical carnivore, feeding mainly on insects in the wild. It is mainly distributed in Asia and Southeast Asia, with greater numbers in the waterside rainforests of Thailand, Malaysia, and Indonesia.

2 Physical Characteristics

The fire crest lizard is little known in the Asian pet market. It is the largest of the medium-sized lizards, with an ideal adult length of 30-40 cm. Because this lizard is quite aggressive, it is best kept alone.

The male fire crest lizard has a rooster-comb-like crest on its head, surrounded by rows of large spiny scales. In addition, it has a well-developed dorsal sail along the center of the back; the scales on the throat and belly are very smooth, the body color is dark green, and the tail has narrow black banding.

3 Care & Husbandry

The fire crest lizard is a typical carnivore, mainly eating insects, and like all lizards it has a high requirement for ultraviolet light, which is normal. It needs an adequate water supply daily. Sexing fire crest lizards is relatively easy; below we introduce the care knowledge for the fire crest lizard. It mainly eats crickets, moths, grasshoppers, mealworms, and even pinky mice as staple foods. Males have larger dorsal crests and dewlaps, with a body color dominated by blue and green; females have smaller crests and dewlaps, with a body color dominated by brown. Most crested lizards are sexually dimorphic, so they are not hard to tell apart.

4 Behavior & Habitat

Anyone who truly likes lizards will learn its basic habits before keeping one, or plan which equipment to buy beforehand, ideally installing everything before the lizard arrives home.

The fire crest lizard is the largest and most aggressive of the crested lizards, so it can only be kept singly or as a pair. They usually perch on large trees or in thickets along riverbanks; in captivity they need a height-oriented arboreal setup with thick branches for climbing. Substrate can be sterile soil alone, or mixed with leaf litter and bark chips. Humidity should be kept above 50%. Crested lizards adapt quite well; although most on the market are wild-caught, they settle quickly in captivity, are robust, and rarely refuse food.
