Bearded Dragon Care Guide: Maintenance & What to Do When Your Dragon Stops Eating
Palvi Palvi 8 min read
Most feeding problems start with the setup. Learn what your bearded dragon needs, from the right lighting and heating to nutrition that keeps it eating.
Key Takeaways
Bearded dragons are calm, curious, and full of personality, and with the right setup, they can live 10 to 15 years. Getting there takes more than a tank and some insects. This guide covers bearded dragon care, from tank setup to a daily maintenance checklist.
Bearded Dragon Care Basics: Build the Right Habitat
Taking care of a bearded dragon involves more than knowing its age. Pay attention to the tank, and keep an eye on your dragon for any changes.
1. Tank size
A young bearded dragon can manage in a smaller tank at first, but adults need at least a 4 x 2 x 2-foot enclosure. If you have the space, go bigger. More room also gives your dragon a chance to move around and choose between warmer and cooler spots.
2. Temperatures
Build a gradient so your dragon can warm up or cool down on its own:
- Basking area: The warm spot should be 95–110°F (35–43°C). For young dragons, it can be slightly warmer.
- Cool side: Keep the other end of the tank at around 75–85°F (24–29°C).
- Night: About 65 to 75°F (18 to 24°C). Most dragons do not need night heat if the room stays in this range.
Pro tip: Measure the temperature with a digital thermometer or temperature gun at the spot where your dragon sits, not the air above it.
3. UVB lighting
UVB lighting is not optional. Your dragon uses UVB rays to make vitamin D3. Without vitamin D3, the body cannot absorb calcium. Over time that leads to metabolic bone disease, a painful and sometimes fatal health problem. Run the light 10 to 12 hours a day, and replace the tube on the schedule the maker gives, often every 6 to 12 months.
Warning: UVB lights can look perfectly normal even after their UVB output weakens. Replace the bulb when it’s due, rather than waiting for it to burn out.
4. Substrate and decor
Go with a substrate that won’t be a hassle to clean, such as tile, reptile carpet, or paper towels. Give your dragon a hide and add a couple of sturdy branches or rocks where it can climb or take a break.
- Enough space for your dragon to move around
- A warm spot for basking
- A cooler area to retreat to
- Separate food and water dishes
- Thermometers to check the enclosure temperature
Avoid overcrowding the enclosure with decorations. Your bearded dragon should still have plenty of open floor space for walking and exploring.
With the habitat ready, the next job is feeding your dragon well.
5. What to Feed: Healthy Eating Habits at Every Age
Bearded dragons are omnivorous reptiles that eat both plant and animal foods. Their nutritional needs also change as they grow.
A juvenile dragon usually needs more frequent meals and a greater proportion of insects because it is growing rapidly. Adult bearded dragons, by comparison, generally eat more plant matter and fewer insects.
| Life stage | Mostly eats | Feeding pattern |
|---|---|---|
| Juvenile dragon | Insects (about 70 to 80% of the diet), plus chopped greens | Insects 2 to 3 times a day, greens offered daily |
| Adult bearded dragon | Greens and vegetables (about 70 to 80%), plus insects | Insects a few times a week, fresh salad daily |
Juvenile bearded dragons grow fast and need more protein. An adult bearded dragon needs far less. Feeding adults too many insects is a common cause of weight gain.
Good staples. Dubia roaches and crickets make good insects. For greens, try collard greens, mustard greens, turnip greens, and dandelion leaves. Dust insects with calcium powder most days, and with a multivitamin once or twice a week.
Foods to skip: Keep avocado, rhubarb, and wild-caught fireflies off the menu. Don’t overdo spinach or kale, as they can interfere with calcium absorption.
Easy size check: Choose insects no bigger than the gap between your dragon’s eyes.
Why Is My Bearded Dragon Not Eating?
A bearded dragon not eating can be worrying, but a temporary change in appetite does not always mean your pet is seriously ill. Some common causes include:
1. Incorrect Temperatures
A cold enclosure can leave your bearded dragon sluggish and less interested in food. Check the basking area first, since your dragon needs enough warmth to digest its meals properly.
2. Seasonal Changes and Brumation
Some adult dragons eat very little when they enter brumation. They become less active during this seasonal slowdown and may spend more time resting instead of looking for food.
However, do not automatically assume appetite loss is brumation. Illness can sometimes look similar. If you are unsure about the cause, consult a reptile-experienced veterinarian.
3. Stress or Environmental Changes
A new enclosure, relocation, excessive handling, loud surroundings, changes in lighting, or other disruptions can affect eating habits.
A new or stressed dragon may need time to settle. Keep its environment stable and avoid unnecessary handling while it adjusts.
4. Poor Diet or Feeding Routine
Sometimes the issue is simply what’s in the food dish. Offering the same foods too often, giving unsuitable foods, or using insects that are too large can cause problems. Missed or irregular meals can also affect nutrition. Make sure the food and feeding schedule suit your dragon’s age.
5. Illness or Injury
Sometimes refusal to eat is related to a health problem. Your dragon may eat less when dealing with an injury, infection, digestive problem, parasites, or another illness. Potential concerns include:
- Mouth rot
- Parasites and infections
- Metabolic bone disease
- Respiratory problems
- Digestive problems
- Other underlying health issues
Look at your dragon's overall condition instead of focusing only on how much food it has eaten. Before assuming there is a medical problem, look at the basics. Check the enclosure temperature, UVB setup, recent environmental changes, feeding routine, and your dragon's overall behavior.
When Should You See a Veterinarian?
A bearded dragon that skips a meal is not necessarily sick. However, persistent refusal to eat, weight loss, weakness, abnormal behavior, or other physical symptoms should not be ignored.
If your dragon is not eating and you cannot identify an obvious environmental reason, contact a veterinarian experienced in reptile medicine.
Veterinary attention is especially important when appetite loss occurs alongside signs of infection, parasites, mouth problems, injury, breathing difficulties, or possible metabolic disease.
Avoid trying to diagnose or treat a suspected illness at home based only on your dragon's appetite.
Bearded Dragon Care Checklist
Good bearded dragon maintenance is mostly routine. A few minutes a day prevents most problems.
Time needed: About 10 minutes a day, plus 30 minutes for a weekly clean.
| Routine | What to Check |
|---|---|
| Daily | Temperature, lighting, water, waste, appetite, activity |
| Feeding | Appropriate insects, vegetables, greens, and supplements |
| Weekly | Dishes, enclosure cleanliness, décor, body condition |
| Regularly | UVB bulb, heating equipment, thermometers, habitat setup |
| When concerned | Weight changes, unusual behavior, illness signs, prolonged appetite loss |
Final Thoughts
Having trouble with your dragon’s appetite? Start with the enclosure. Check the heat and UVB, then make sure you’re feeding foods that fit its age. It’s also worth noticing changes in poop, activity, or how much it eats. If your dragon suddenly eats less or seems off, keep an eye on it, as stress or a health problem may be involved.
Frequently Asked Questions
Q1: Why is my bearded dragon not eating but still active?
Ans: Check the basking temperature and UVB tube first, since low heat or weak light often reduces appetite. Shedding, stress, and a boring menu are also common causes. If a juvenile skips food for more than a day or two, or an adult for much longer, call an exotic vet.
Q2: Can a bearded dragon go a week without eating?
Ans: An adult in brumation can, since its metabolism slows in cooler months. A juvenile cannot, so call a vet if a young dragon refuses food for more than a day or two. An adult that is not brumating should also be checked.
Q3: Is it normal for my bearded dragon to sleep all day and skip meals?
Ans: It can be, if your adult dragon is brumating and its stool and weight look normal. A brumating dragon often sleeps for days and eats little. If it seems weak, loses weight, or has other symptoms, see a vet.
Q4: How do I know if my UVB light is still working?
Ans: You can’t tell from the light alone. A UVB tube can keep glowing even after its UVB output has weakened. Follow the brand’s replacement instructions, usually every 6–12 months. A UVB meter is the best way to check how much UVB the tube is actually producing.
Q5: How long can a baby bearded dragon go without food?
Ans: Baby bearded dragons need regular meals while they’re growing, so going without food for more than a day or two isn’t something to ignore. If your baby refuses food or seems weak or unusually tired, contact an exotic vet.
Q6: How often should I take my bearded dragon to the vet?
Ans: An annual vet visit is a good routine for a healthy bearded dragon, including a parasite check. Don’t wait for the next check-up if your dragon stops eating, loses weight, acts unusually tired, has odd-looking poop, or shows swelling, shaking, or a soft jaw.
