How Much to Feed a Bearded Dragon
How much to feed a bearded dragon: portion sizes for insects and greens by age, the 10-15 minute rule, avoiding overfeeding, and how to judge a healthy weight.
Knowing how often to feed is only half the picture. The other half is how much, and getting the portion right is what keeps your bearded dragon at a healthy weight. Feed a baby too little and you stunt its growth; feed an adult too much and you set it up for obesity and fatty liver disease. The good news is that you do not need to count every insect. A simple feeding-window rule, combined with daily greens and regular weight checks, makes portioning straightforward. Here is how to dial it in at every age.

The 10 to 15 minute rule
The simplest and most reliable way to portion insects is to feed by time, not by count. Offer appropriately sized, dusted feeders and let your dragon eat as many as it wants over about 10 to 15 minutes, then remove any leftovers. This lets your dragon self-regulate based on its real appetite, which varies day to day with temperature, shedding, and growth. A growing baby will eat a lot in that window, while a satisfied adult will eat a modest amount. It also prevents loose insects from lingering in the enclosure.
Portion guidelines by age
| Life stage | Insects per feeding | Insect frequency | Greens |
|---|---|---|---|
| Baby (0 to 5 mo) | As many as eaten in 10 to 15 min | 2 to 3 times daily | Small portion daily |
| Juvenile (5 to 12 mo) | 10 to 15 minute window | 1 to 2 times daily | Growing portion daily |
| Sub-adult (12 to 18 mo) | Modest portion | Daily to every other day | Large portion daily |
| Adult (18+ mo) | Small portion (about 10 insects) | 2 to 3 times weekly | Generous daily, main food |
These are starting points. Babies and juveniles can eat a surprising number of small insects because they are growing rapidly, and that is healthy. Adults need far less, with the plate weighted toward greens. Throughout, size each insect to the space between the eyes to keep feeding safe.
How much salad to offer
Greens scale up as your dragon ages, because plants go from a minor part of a baby's diet to the main course for an adult. For an adult, offer at least a small handful of chopped staple greens and vegetables each morning, with the aim that your dragon eats most of it. If the salad disappears quickly, offer more next time. A shallow dish keeps the salad clean and off any loose substrate, and removing it before evening keeps it fresh and prevents waste.

Avoiding overfeeding
Overfeeding is mainly an adult problem. Because adults need so few insects, the common mistake is continuing to feed insects daily out of habit, which floods the body with protein and fat. The result is obesity and fatty liver disease, both of which shorten lifespan. To avoid it, commit to the age-appropriate schedule: by adulthood, insects are a few times a week and greens are daily. Limit fatty treats like superworms and waxworms, and resist the urge to feed more just because your dragon begs, since dragons will happily overeat sweet or fatty foods.
Judging a healthy weight
Let body condition guide your portions. A healthy dragon has a gently rounded belly, a full but not bulging tail base, and hip bones you can see but that do not protrude. Warning signs of obesity include fat pads bulging above the eyes, a swollen jowl, and a thick, fat-laden tail base. Signs of being underweight include a sunken belly and sharply prominent hips and ribs. Weigh your dragon regularly on a kitchen scale and track the trend over time. If the weight is climbing on an adult, cut back insect frequency and fatty treats; if a young dragon is not gaining, increase feedings. Steady, age-appropriate portions plus regular monitoring are the simplest path to a healthy, long-lived dragon.
Frequently Asked Questions
How much should I feed my bearded dragon?
Use the 10 to 15 minute rule for insects: offer appropriately sized feeders and let your dragon eat as many as it wants in that window, then remove the rest. Babies may eat 25 to 50 small insects across a day, juveniles fewer, and adults only a small portion two to three times a week. Greens are offered daily in a portion roughly the size of your dragon's head or larger.
How many crickets should a bearded dragon eat a day?
It depends on age. A baby might eat 25 to 50 small crickets per day spread across two or three feedings, a juvenile around 25 to 40 per day, and an adult only about 10 appropriately sized insects two to three times a week rather than daily. Always use the 10 to 15 minute feeding window as your real guide instead of a fixed count.
Can you overfeed a bearded dragon?
Yes, especially adults. Overfeeding insects leads to obesity and fatty liver disease, which shorten lifespan. Babies rarely become overweight because they burn energy growing, but adults fed insects daily or given too many fatty treats gain weight quickly. The fix is to shift adults to a plant-heavy diet, limit insects to a few times a week, and watch body condition.
How do I know if my bearded dragon is a healthy weight?
A healthy dragon has a rounded but not bloated belly, a tail base that is full but not bulging with fat, and visible but not protruding hip bones. Obesity shows as fat pads above the eyes, a swollen jowl area, and a thick tail base. Underweight shows as a sunken belly and prominent hips and ribs. Weigh your dragon regularly to track trends.
Should I leave food in my bearded dragon's tank all day?
Leave fresh greens available during the day, but remove them in the evening before they wilt. Do not leave loose feeder insects in the enclosure, since crickets can nibble a sleeping dragon and stress it, and uneaten insects hide in decor. Offer insects in a timed feeding, remove what is not eaten, and refresh the salad daily for the best results.
How much salad should an adult bearded dragon eat?
An adult should eat a generous daily salad, since plants make up about 80 percent of its diet. A practical portion is at least a small handful of chopped greens and vegetables, offered fresh each morning, with the goal that your dragon eats the bulk of it. Adjust upward if your dragon finishes it eagerly, and always provide variety from staple greens.
