Honest answer? People are boring, there are thousands of species of lizards and when you get someone asking for suggestions on what they could keep there are the obvious three that pop up( Bearded Dragon, Crested Gecko and Leopard Gecko ). If they then want something a tad more unusual they are lucky to get 10 different answers. The only reason I can see for the amount of the '3 starter lizards' that are out there is lack of imagination and research. When you think about it how fun are the '3 starter lizards' to keep? Not very in my opinion. There are so many more intriguing and exciting lizards to own that are overlooked just because they don't often come with fancy paint jobs.just a curious question as to why you see loads and loads of crested geckos around but hardly any gargoyles?
