I have a young male veiled chameleon he is probably 5 months old. I have him in a 24"x24"x48" screened enclosure with a ficus and pothos. He is showing normal light green coloration and eating and drinking well. I have a 24" uv light strip and a 100 watt basking bulb. I noticed recently on his back he has a small black spot at the very top middle of his back. Is this a burn? I am mainly concerned whether or not it will go away. I have moved the basking lamp so he can not get so close.
