Help!

He may have bit it. Is he still using it to eat? Sleeping during the day is bad, has he been checked for parasites? May be worth a trip to the vet.

You need to start a thread under the Health Clinic section which is under Forums (top left). In your thread please fill out the Ask For Help Form. http://www.chameleonforums.com/how-ask-help-66/
Also post some pictures. In the meant time look for a good reptile bet that has experience with chameleons and get her an appointment
