So the shop I work at has a gecko which is labeled "Vorax Gecko," but none of us really knows much about the species so my manager told me to go online and research about it to make sure we're taking care of it correctly. Well i'm online and i keep seeing posts about mix-up's of the species and what not.... that Vorax's are extremely rare and people often mis-name the more commonly available and imported species Marginata as Vorax's. So i'm really not sure what he is then... i'm assuming the Marginata since the Vorax's are so rare and expensive. 

But my question is how can I really tell the difference between them? I want to confirm what this guy is and then know how he should be taken care of. So can anyone describe to me the differences and such? ALSO, all i ever run into are fricken bulletins, can anyone give me some links to some articles and such about any of these geckos? I need to learn this stuff. Thanks a bunch! and sorry for another looong post. :)
