Hi there, I have had my chameleon for around 5 months, he is roughly 17 weeks old. He has been fine since I have had him but always been a bit wary around me. For the last week he hasn't been eating as I have seen, plus has been very temperamental and has been hissing at me and trying to bite me. I have been feeding black crickets for the last week rather than brown crickets and he hasn't taken much interest in his crickets or his veg and is acting very out of character. He has been displaying dark brown colours and I'm not sure what is up with him. Does anyone have any advice?!
