CAPTIVE CARE SHEET SPECIES: BOSC'S OR SAVANNAH MONITOR Varanus exanthematicus
Grows to a maximum length of 100CM
DISTRIBUTION: Bosc's monitors are the most commonly available monitor lizard in the pet trade. All those in shops are imported wild caught or captive farmed specimens, from Togo or Ghana. Hatchling Bosc's are about 15cm in length, adults reach around 100cm. Records Kept in the USA show these animals can live in excess of 15 years.
HOUSING: When housing Bosc's it is important to remember that they grow rapidly from their hatchling stage. The larger the vivarium you can provide the better. For an adult a minimum size would be 120 x 60 x 60 cm. The structure should be sturdy, and front opening, with glass that is shatter proof (4mm+). Bosc's have extremely strong tails that they whip when agitated. Substrate for the cage can be any of a variety of materials, such as wood shavings,chippings or bark even gravel or newspaper. It should be easily replaceable, as Bosc's are messy when they defecate.
Bosc's like most large lizards need to feel secure, so a shelter must be provided. This can be as simple as a cardboard box, or more decorative like cork bark tube or a ceramic drain pipe.
These animals come from hot and arid countries.The day time temperature is high 85-90F(29-32C), night time temperatures can be allowed to drop by 10 - 15F(6-8C). All cages have a hot or cold spot it is a good idea to find out where these are using a min max thermometer. There are several heat sources to chose from such as heat mats, tube heater and heat lamps. it is best to find the one that heats your viv the most economically for its size. I have great success with heatmats.
Bosc's do not require UV light. Artificial light should be provided to establish definite photo periods that may aid breeding.
DIET: Water should always be available in low sturdy dishes to avoid spillage's, the ideal would be a dog bowl. They do drink regularly even though the are from arid regions. They do like to have a soak, this however leads to defecation, do not allow this to stand around and disinfect before reuse. Bosc's are not usually fussy about what they eat, which can lead to problems of obesity when adult. Hatchlings will eat crickets, mealworms, baby mice and act food. It is advisable to add a mineral and vitamin supplement such as Nutrobal or Reptivite. The size of prey should increase as the animal grows, hatchlings and animals up to 30cm should be fed every 2-3 days on mice with the occasional addition of crickets and cat food. Some like boiled eggs as a treat but it can be messy. Sub adults and adults should be fed 1 -4 adult mice or 1/2 a tin of cat food per week. If the animal appears to be getting to fat then adjust the amount. Live crickets and locusts given on an occasional basis provides some exercise.
HANDLING: Once you have bought your monitor, leave it alone in it's cage for a few days to get used to the change. Avoid moving suddenly around the animal. All Bosc's will bite if provoked or threatened. The threat display consists of a thrashing tail and a puffed out throat and a loud hiss. It may flatten the body either ventrally or laterally towards the aggressor. If the bosc does bite it has the ability to lock its jaws closed.
When handling a Bosc do so firmly and without hesitation. A thick pair of gloves may help to start with. Grab the Bosc behind the head to avoid bites and support the body with your other hand. If large enough tuck the tail under your arm to prevent thrashing. With regular handling most Bosc's will calm down.
