So I came home today from work, and my normally very laid back, usually always bright green and chill (eats from my hand even while holding him) veiled chameleon is in a rather grumpy mood! I haven't done anything except put some food in his enclosure and water him but he's now sitting under his light, all darkened up, like a forest green color, with his dark spots on display, beard extended and puffed up. Not sure what his deal is but I hope it's just a mood and not a sign that somethin could be wrong. Wow, as i'm writing this i just watched him like, wiggle his whole body and open his mouth wide like a yawn, and his spots darkened. Any ideas?
