Why is my chameleon turning dull grey and black? Is he sick?

Updated on September 23rd, 2025

My 2 year old pantheon chameleon started losing colour on his head about two weeks ago. This has now spread around his whole body so he is very dull grey and black for the last few weeks. He has a 4/5 ft high tank, with heat lamp and uv lamp, he has crickets daily and calcium and D3 too. He’s eating and drinking fine, he’s been in the sun and had vitamin supplements to try and help. He still remains very dull apart from one patch on his body. I’ve attached two pics of him now and one of him befo

Are you sure he isn't going into a shedding period?
Confirm proper environmental parameters, especially heat and UVB lighting. Low temps may cause stress which could cause him to become dull. Replace the UVB lights if older than 6 months. Mist him daily and use hygrometers in his enclosure to confirm proper humidity levels.
Monitor for lethargy or decreased appetite. If necessary, have him examined by your veterinarian or a vet experienced in treating reptiles to diagnose illness or injury.

    Check the temperatures in the enclosure. Low temps can affect appetite in reptiles. Soak him in a warm 50/50 solution of water and unflavored PediaLyte for 20-30 minutes every few days. This will provide warmth and hydration.
    Offer appropriately sized prey after he is warmed up. You can supplement with Fluker's Repta-Boost.
    Look in around his mouth for any symptoms of illness or injury. This may include redness, swelling, discharge or bleeding. See your veterinarian or a vet experienced in treating reptiles if you see anything suspicious or if he doesn't begin eating.

    Look in and around his mouth for any signs of infection or injury. This may include redness, swelling, discharge or bleeding. See your veterinarian or a vet experienced in treating reptiles for an exam if you see anything suspicious. Likewise, if symptoms persist or worsen, see your veterinarian. Unfortunately, the symptoms described are non specific with multiple potential causes.

    He may be stressed at the change in environment. You'll first need to determine what negative stimuli, if any, are present. The enclosure should be in a low traffic area away from drafts, loud noises or direct sunlight. If he's in front of a window, make sure he can move out or the light whenever he wants.
    Check environmental parameters as well. Low temps, insufficient lighting or improper humidity levels can result in stress.
    Feed appropriately sized prey. N bigger than the space between his eyes. Gut load them for 24 hours prior to offering to maximize nutritional value. Soak or mist him with a warm 50/50 solution of water and unflavored PediaLyte to prevent or treat mild dehydration. As a new pet, consider having him examined by your veterinarian or a vet experienced in treating reptiles to confirm good health or to treat any pre existing conditions.
