We have had this chameleon for 2.5-3 years. He has always been healthy. A few days ago I noticed this blister on his head. The only thing I have changed is his uv bulb, about 3 weeks ago. It is a lower wattage than the old bulb. The only thing I can think of is a burn from the new bulb.
Any one know what it may be?
Or how to treat him?
