Black rough-necked monitors are extremely arboreal and will benefit from a tall cage and numerous branches mounted both horizontally and vertically. Hide boxes and retreats are also needed. Newly imported black rough-necked monitors are usually dehydrated and heavily loaded with parasites, therefore the administration of fluids and a fecal analysis by a vet are definitely in order. Captive black rough-necked monitors will accept earthworms, lizards, birds, eggs and mice. Monitors require temperatures ranging between 82 and 90 degrees Fahrenheit, with a warmer basking spot (up to about 95 or 97 degrees Fahrenheit). Nighttime temperatures can be lowered to around 70 or 75 degrees Fahrenheit. A thermal gradient is recommended.
