darkness???????? jmo
they can turn dark for a # of reasons (including stress), but turning dark during or after basking or during sleep, can also be part of their thermo regulation process to absorb & conserve heat. as long as its urates and feces look & smell healthy, and it isnt acting stressed otherwise, then i wouldnt be overly concerned. this seems more common with younger jacksons than it does older ones. imo the older they get, the less likely they are to darken for thermoregulation. ime, healthy adult xanths that are happy with their enviroment, dont turn dark that often. i would keep an eye on its feces and urates and a close eye on its behavior in general. it could be just as simple as getting stressed by the trip outside, or it could be an acclimation issue if its wc, imo, any xanth bought in Hawaii is more than likely wc (or at least hatched from untreated wc), and likely has parasite issues, so if you plan on keeping it long term, then a fecal float by a qualified herp vet is probably in order. if it starts turning dark regularly, and that darkness is accompanied by loss of appetite, unhealthy looking or smelling samples, any sort of trembling, unsteadiness, or unusual cham behavior, then there is likely other problems at hand. sorry i couldnt give more of a definitive answer, but there are a lot of variables (including the individual cham its self), more info would be helpful jmo
