General information
Varanus glauerti lives in Northern Australia. Especially in the Kimberley area that's why glauerti's are also known as the Kimberley rockmonitor. You mainly recognize a glauerti by it's long black and white tale. This tail is about 2/3rd of it's entire length, furthermore it has a very small flat head and a long neck. In general a glauerti monitor is a very slender monitor. And with it's beautiful red/rusty coloring on the back it's a stunning animal.

These monitors live in the rocky area called the Kimberley's. There are also forests there. The temperatures in their surrounding vary from 45C during the day to 15C at night. Therefore you need to use extra heat for your cage as the regular temperature will do. The animals live in the forest arear so humidity level should be around 40% to 80%. Also these animals feel comfortable is very narrow hiding places.

The total length of the glauerti is 80 cm head to tail. About 2/3rd is tail so the head and body are about 30 cm. The base color is red/rusty with on it white/beige dots. In some cases these dots are nicely lined up on the back but certainly not in all cases. The tail exists out of black and white rings. The hind legs are black with white dots. The most extraordinary about this specy is that it's very slender and has a flat head, long neck and a long tail. The difference between males and females in young animals is hard to tell. As they get older you can see a few differences. The males have enlarged pores on their tails at about 2 cm under the cloaca. Also males have a more distinctive pattern as the females and they have a bigger and wider head. Also males tend to be larger than females in general.

I keep my glauerti's in a cage that is 160cmx62cmx85cm. I made a backwall of styrofoam and cement so that the animals can climb away. I also use corque logs and wooden elements so they can climb and hide. On the floor I use bark but perhaps sand can be used also. I use a T-rex UV heat lamp of a 100watt en a 60 watt heat lamp. With these two lamps I provide UV en 2 sunbathe spots that are approximately 55 C and 45 C. I leave the lights on for about 12 to 13 hours. A waterbowl is a must for these animals as they drink a lot.

I feed my trio 3 times a week crickets and one baby mouse or baby rat. Sometimes I vary using grasshoppers. I spray the cage every week and fill the waterbowl daily. I try not to let the humidity level get too high as I have a large waterbowl which already adds to the humidity level. These animals are fast and smart so be carefull they don't escape. Glauerti's aren't diggers so you don't have to use a lot of bark or sand. Just make sure there are plenty of places to hide. These animals aren't particularly shy but providing enough hiding places will make them more comfortable and show themselves more often.

Glauerti's are ready for breeding after about 9 months to 1,5 years. It's important to either seperate the animals or give them a winterrest. I prefer wintersleep as seperating them hasn't worked with my animals so far. Wintersleep lasts about 2 months in which the animals get about 6 to 7 hours of light a day. They become less active and pretty soon they will start mating. The male and female start curling their tails and the male walks over the female nudging her and flicking his tongue very often. After that the typical lizardmating follows where the male bites the female's neck and folds his tail around hers. The female carries her eggs for about 6 weeks, after that she will lay them in an undeep nesting spot.

Incubating glauerti egg is rather easy, I have been most succesfull with a mix of 1:1 vermicullite/perlite/water) The eggs will lay for about 100 to a 140 days in the incubator at temperatures between 28 to 30 C I try to removed already hatched babies as quicky as possible as they are instantly very active and run over the other eggs.

Hatched babies are exact copies of their parents. After about a week they start to eat. They drink from the start. I feed them small sized crickets, they can eat anything smaller than their headsize. After a while they can become territorial if they do they must be seperated. If you are interested in keeping 2 or 3 young glauerti's togethe I advice you to put them together quickly so they don't have to fight so much over who's at the top of the foodchain. Other than that you keep babies the same way as adults except that you spray them daily and feed them more often using a vitamin/calcium powder.

Glauerti's are fascinating animals and suitable for people who are a bit more experienced. As with every reptile it is important to gather and read information first so this caresheet is a good start. The animals are not very demanding and relatively easy to keep. Breeding is also doable and fun. Glauerti's are very active and so a great choice.
