Gekko ulikovskii, or the Golen Gecko, is native to the humid, tropical rainforests of Vietnam. Males grow to around 7", while females stay around 5" to 6". Golden geckos do not like to be handled. They are somewhat hyper and can stress easily. They can and will bite when bothered but if they are handled enough they can be tamed. As a defense mechanism the tail can detach to confuse the predator, giving the gecko time to escape.
