Common name: Northern ridge-tailed monitor.
Described: 1942 Mertens.
Primordius is one of the smaller species in the Odatria genus. They can normally reach a length of up to 30cm
Primordius can be kept in a 100x50x50cm ( length X wide X high ) cage.
As other monitors they are active during the day, and will use all the space avaible to them. So it is important to give them as much usable surface as possible. That can be achieved with fake rockwalls and cork tubes.
I like to use a sandy soil for my primordius, but not types like beach sand that is very loose when dry and makes it harder fo the animals to move. A deep substrate i a good idea as it gives the female plenty of opportunities for a good nest site.
Light / heat.
LED tubes are used as main light.
UV is provided by a single UV tube with a reflector.
As basking light we use nornal halogen spot bulbs.
The daytime temperature inside the cage is 28-32c.
Basking area should be around 45-50c.
Primordius is mainly insectivore lixards, and our diet for them is made up by the following: crickets, wax worms, grasshoppers and red runners.
Primordius can be a pretty shy monitor, and loves to stay inside thin cork tubes,
