Well, mine were collected from the mainland, cap est on the Masoala peninsular. Nosy Boraha come from the Island near by. It is possible that us Europeans are all wrong and these cant be classified as Masoala but i find this unlikely. Try to find pics of them, I bet there arent many out there. I would take a stab in the dark too and say that i dont think anyone has them in the US. Show me pics if im wrong!
Also, without trying to turn this into an argument, Only a few months ago you were asking what was the difference between Nosy Faly and Ambanja so I think perhaps your confused about this one too. Yours looks a lot like a nosy radama i had until recently, ill post a pic up later so you can see what i mean. Its too pink to be tamatave and not green enough to be like the mainstream Masoala i see on here all the time.
Also, check out cleanline chameleons, they have cap est on their webpage.
