Hi, I've got a Graceful chameleon thats about a year old. The person I got it from told me it was a male, but I don't know for sure. He/she is in an open screen enclosure with live plants, misted and dripped daily. He's always been well, however yesterday evening he turned dark and began walking all around the cage, the ground, the walls, not stopping. I know this means he is uncomfortable, not happy, etc. (I've had a similar situation happen with another cham who wanted out during a storm, but it was isolated). Anyway, I let him out and his color eventually returned to normal. However everytime I put him back in his cage, after he warms up, he'll turn dark and start pacing again. I fed him today, and he ate a lot, but then started again. Outside of the cage, he's sleeping at night, and walking around all day. What's going on? What should I do? Thanks so much in advance-
