I've had my Jackson for almost a month now and hes been just fine by what i can tell. His color was good, he had his first shed, and all was going well I thought even after 3 habitat shifts in the last weeks (i had some mistakes that needed rectifying). Two days ago i woke up and looked at him and he was BLACK! Needless to say I was freaked and got him to the herp doctor ASAP. Now he is only a darker color in the day, once his night cycle starts he reverts to his verdant greeny self. I thought maybe his humidity was off(as doc recommended he had shed retention) and after rectifying this with a cool mist fogger I hoped for a change. Nothing. He still a darker cooler in the day and green at night. I have(from what i can tell) a decent set up for him but he seems to not want to change color in there ( at the doctor he was green as a leaf, even when handled) and I cant seem to narrow down the culprit. I have a UVB, basking light, a variant in temperatures through out the cage, I spray his feeders and gut load them. I monitor his heat and humidity in both the day and night (well within boundaries, although there is a slightly higher drop in nighttime temps, about 5-10 degrees lower than i like). I am at a loss. I was recommended maybe a ceramic heat emitter bulb for at night to keep him warmer but am afraid of not meeting his proper digestion temperature at night. Any suggestions? I know hes telling me something with his color but I cant seem to figure out what. Would you please help out this new Jackson keeper? I will post pics when i can of whats what at a latter date. Thank you for your time.
