I think he is talking about the Chameleon's left arm. It appears broken.Im not clear what you are asking. Does he leave his tongue partially out / mouth slightly open all the time? if yes, that is indeed an indicator of a problem. His head looks odd in that picture.
again I ask - All the time, or just occasionally?His mouth is partially open with the tip of his tongue out!
Iv had to change his bulb as the 60w heat bulb would only produce 76f and was told that could be why so I'm using a 75w bulb which brings it up to 85-90
Looks like besides an issue with his tongue and mouth that he is suffering from MBD - Metabolic Bone DiseaseI think he is talking about the Chameleon's left arm. It appears broken.
Mouth open is a bad sign, often associated with MBD / insufficient calcium in diet. or an inbalance. I wouldn't suggest Nutrobal at every feed, but rather once or twice a week and the rest of the time a phosphorous free, vitamin free calcium powder (like sticky tongue farms Mineral - O).His arms etc are fine. Just the tongue which is the some times slightly open but the tongue is always out very slightly which keeps mouth open.

IMO I think he has hurt his tongue on a plastic leaf
