biggest one i currently have is 13.5". Max WC is around 16" but in captivity around 12-13 inches and captive breed around 10-12 inches. The first year they grow fast usually slowed down at 10". Then another 2-3 years to achieve 13"+.

Please do a search as there was a tread very very similar to this question.
