Varanus panoptes horni
Common name: Argus monitor.
Sub genus: Varanus.
Described: Böhme 1988.
Another species i used to keep many years ago.
Varanus panoptes horni is a rather massive build monitor lizard, and therefore needs a rather large cage. The cage i had for my pair measured about 350x150x150cm ( long X wide X high ), and I would not keep this species in a smaller cage then that. They are an active ground living monitor so obviously they have a huge appetite, and loves to really get heated.
So as basking area they had a number of flood bulbs, to create a large enough basking area so they could fit the entire body under it. Basking temperature was about 55c. The all over csge temperature was maintained at 28-30c during the day and 20-24c during the night.
The decorations was made with logs, mainly to create visual barriers, as the pair was kept together all year round.
Panoptes are not picky eaters and will more or less eat anything that moves and fit in their mouth. The food they had was mice, rats, chicks and other small birds, grasshoppers, roaches of different species, and sometimes chicken heart.
As for breeding, not much had to be done. They did have it a bit cooler during winter due to me living in a colder climate. The amount of food was also reduced during winter.
In spring when outside temperatures where going up, the amount of food was also increased, and mating would start in late spring. They would lay eggs a number of times during the warmer period of the year. A big tub with a lid on was used as nest box and was happily used by the female. Because the female was smaller then the male, the entrance to the nest box was made so that only the female could enter. This served two purposes, one, it created a good nest site for the female to lay eggs without being disturbed. Two, since the nest box was inside the cage all year round it also served as a retreat for the female, as she would be able to get away from the male if she needed.
Incubation of the eggs where pretty much same as for other monitors. At the time I used candy boxes where holes where cut in the top. Incubation substrate was vermiculite mixed with water at a ratio of 1:1 by weight.
The eggs where incubated at a constant temperature at 28c.
