The Crotaphytus genus is divided into 9 species, but all have the "necklace" that gave it its name. But the most common is Crotaphytus collaris, which has a total length of 30-35 cm. You can easily tell the difference between males and females, the males are more brightly colored and have a greenish base colour, whereas the females have a grey-brown base colour. When the females are pregnant, they get red markings and bands which disappear after laying eggs.
All collared iguanas are diurnal and love sunlight and high temperatures. They are insectivores and use their powerful hind legs to lunge to catch prey. They are good hunters and very active, spending most of their time on rocks or in caves.
Keep in terrarium
They need a lot of space as they are very active. For a trio with one male and two females, the terrarium must be at least L: 150, D: 70 and H: 70 cm. The terrarium must be decorated with a desert theme. Their bottom layer must be sand and they must have access to small hiding places and climbing opportunities. Of course, they must also have a lot of light and heat. In the warm end of the terrarium, the temperature must be 35 degrees and with a small local heating area of 50-60 degrees. This can be achieved with a fluorescent tube with UVB and a heat bulb of 40-60 watts. At the cold end, the temperature should not move much above 30 degrees. They must always have a water bowl standing with fresh water.
In the wild, they primarily eat insects, but can also take smaller lizards. Can be fed crickets, grasshoppers, cockroaches, wax moths, mealworms and other small insects no wider than its mouth. Periodically, this iguana can eat very little or nothing at all, there is no need to worry as they will soon eat normally again. All feed insects must be shaken in vitamin and mineral powder, and pregnant females must have extra calcium.
Signs of illness
Half-banded iguanas get sick quickly if they are too humid or if they are not kept dry, bright and warm. If you fulfill their needs, there would otherwise be nothing. The animals should be very active, have bright colors, appear fresh and eat daily. If they show different behavior for a longer period of time, a veterinarian should be contacted.
At the pet dealer, it is almost always wild-caught collared iguanas, so it would be best to buy from a breeder.
If you want to be successful with breeding, it requires a winter rest of 10 weeks, where the temperature is lowered to 10-12 degrees and the day length is only 6 hours. Mating will then take place right after the winter rest, when about 8 eggs are then laid.
Hatching of eggs
The eggs must be incubated in moist vermiculite at 30 degrees, for approximately 60 days.
The cubs must have the same feed as the adults, just in the appropriate size. Extra lime must be added to these fodder animals.
