The young ones are always not so colorful, so that might be why he looks sorta grey. I wouldn't be feeding mealworms a lot though as they are high in fat and hard to digest for chameleons. You have a beautiful little boy, good luck! :D
My temp gun just came. His basking is 83.5, and the ambient ranges from 78.5 to 76 depending on the location of the cage. He did not like me sticking my hand in his cage xD
It's coming Wednesday, but I bought a cheap little one till it comes, 84 and 83 in his basking. I just walked over to the tank to see the temps, and I saw the little stinkers head :p:ROFLMAO:
