The oldest one I can remember at the moment was a male veiled...he was over 8 1/2 years old when he died. I wish I could say that some made it to 10...but I don't think it was me you are thinking of Chameleontario. Thanks for the comment though!
The oldest veiled female that I recall lived to be 7+....but most of the veiled females make it to 6+ years.
I have had quite a few C. chameleons that made it to 6+ years old (both male and female).
There are other species that I can't get to reproduce and/or can't hatch the eggs from and that I can't hit those ages with either.
Its frustrating. Many of them are WC adults when I get them though. Its amazing how much there still is to learnafter all these years of keeping chameleons!
