[Gecko] Rhacodactylus Chahoua

[NBemmer]

Hi all
    I have some questions pertaining to the differences between Pine Island and Mainland Rhac. Chahoua.  What are the size/color differences between the 2?  Which is the most common and how rare is the other form in the US?  Also if anyone has any other info about the differences between the 2 that would be great.  Thanks
Nate
