Why is my bearded dragon gaging, black beard, and not eating?

Updated On September 23rd, 2025

My friends bearded dragon is gaging, had a black beard and isn't eating. They have been feeding him mealworms,superworms, crickets and strawberries. They said it started a month and a half ago They said she's also acting lethargic. They said this in exact words. "In terms of mealworms we give her a small bowl and she eats about 3-5. With super worms we tried to feed it to her once but she rejected it. Let me take the pictures." If you need anymore info let me know.

Her diet is not nutritionally balanced. An adult beardie (12 months and older) should be eating mostly fresh greens and vegetables, about 75-80% of the diet with the remainder comprised of protein (crickets, dubia roaches, etc). For juveniles, the percentages are reversed. All food should be appropriately sized to make eating easier. The rule of thumb is to offer no greens or prey that is bigger than the space between the eyes. A multivitamin and a calcium supplement are also critical to good health. A bearded dragon also need appropriate temperature and UVB lighting. There should be a cool side, warm side and a basking area. The UVB light should be unobstructed and no more than 14-16 inches from th3e surface of the tank. You can find specifics for diet and environment here: http://www.anapsid.org/bearded.html http://www.peteducation.com/article.cfm?c=17+1796&aid=2730 The gagging may be diet related or not. The black beard is a sign of stress. These symptoms could be nutritional, environmental or medical in cause. Ideally, she should be examined by an experienced herp veterinarian. For now, correct any environmental or nutritional parameters if necessary. Soak her in a warm 50/50 solution of water and unflavored PediaLyte for 15-20 minutes daily. This will provide warmth and hydration. If there are constipation issues, a gentle abdominal massage (front to back) during the soak may stimulate defecation. If the behavior persists or worsens, a physical exam with a vet would be strongly recommended. Submit a stool sample to diagnose intestinal parasites.
