#1 - Take out the green substrate. It will get all nasty and soggy from the water you spray in there (you DO mist him with water DAILY, right?) and that will create bacteria, which is bad. So take that out.
#2 - What kinds of lights are you using? Do you have both a UVB bulb and a basking heat bulb? It's a bit hard for me to tell from the pics
#3 - The standing water dish...Is that a water dish or a waterfall? It looks like a waterfall because I believe that is the power cord to it that the cham is hanging onto ya? Chameleons don't typically drink out of a water dish, and you would be super lucky if you found your chameleon will do this at all. It looks like that is his only option with his cage though. Not good. Standing water dishes collect bacteria, so do you ever clean it? You need a dripper or a misting machine to put water into his cage to drink, not just a water dish. There needs to be water running down the leaves of plants and such, as this is the best way for chameleons to drink. They are attracted to moving water running down plants. Which brings me to number 4....
#4 - Where are all your plants yo? You NEED plants in there. These animals live in the jungles where there are lots of trees and plants. All you have is two rocks which he will probably never crawl on, and a single vine. That is literally the only thing for him to climb on. That's like parking you on the couch for your whole life and that is the only place you are allowed to be. You'd hate that. Add more horizontal vines. Add plants. Lots and lots of plants. Otherwise, there is nothing for the water to collect on for your chameleon to drink. And without more branches or vines, there is nowhere to explore or nowhere to go to regulate his body temperature. He is probably hiding up on that cord because that is the only other place he can go besides that single vine.
#5 - How are you monitoring his temperature and humidity in the cage. Or should i ask..... ARE you monitoring his temperature and humidity? I don't see a gauge for either one in his cage. It's essential to know what the humidity is, because you need to be spraying his cage each day to keep up the humidity. For the love of all things holy, please tell me you ARE misting his cage every day?
#6 - What do you feed him? Like, what kind of insects? Do you dust your insects with a the proper calcium supplements and vitamins? Do you know HOW to dust your insects?
#7 - Honestly probably shouldn't have him in a cage that has gunk on the walls. You have no idea what that gunk is or what it will do to the cham if he ingests it. To each his own I guess, but that's my honest opinion...
