How Many Dubia Roaches to Feed a Bearded Dragon | Feeding Guide
Knowing how many dubia roaches to feed a bearded dragon is one of the most important parts of keeping them healthy. Feeding too little can lead to stunted growth and malnutrition, while feeding too much can cause obesity and long-term health issues.
For Australian reptile keepers, dubia roaches are one of the best feeder insects available due to their high protein content and ease of digestion. This guide explains how much to feed, what size to use, and how to balance live food with greens. For a broader overview of feeder insects, see our complete guide to feeder insects in Australia.
Quick takeaway: Young bearded dragons eat more insects than adults. Feed appropriately sized dubia roaches in controlled amounts, and balance with greens as they mature.
Understanding Feeding Requirements
Bearded dragons have different dietary needs depending on their age. Younger dragons require more protein to support their fast growth, while adults need a more balanced diet with a higher proportion of plant matter.
- Juveniles: high protein for growth
- Sub-adults: balanced mix of insects and greens
- Adults: mostly greens with controlled insect intake
Dubia roaches are ideal because they provide dense nutrition without excessive fat.
What Size Dubia Roaches to Feed
Choosing the correct size is critical for safety. A general rule is that the roach should not be wider than the space between your bearded dragon’s eyes.
- Hatchlings: XS to Small
- Juveniles: Small to Medium
- Sub-adults: Medium to Large
- Adults: Large to XL
Width matters more than length because dubia roaches can change shape depending on feeding and hydration.

How Many Dubia Roaches to Feed
The number of dubia roaches depends on the age and size of your bearded dragon.
- Hatchlings: 10–20 small roaches per feeding, multiple times per day
- Juveniles: 10–20 roaches per feeding, 1–2 times daily
- Sub-adults: 5–15 roaches per feeding, once daily
- Adults: 5–10 large roaches, 2–4 times per week
These are general guidelines. Appetite, metabolism, and activity level will affect how much your dragon actually needs.
Why Protein Intake Matters
Dubia roaches are high in protein, which is essential for muscle development, growth, and overall health in bearded dragons.
However, too much protein can lead to:
- excess weight gain
- strain on internal organs over time
- imbalanced nutrition if greens are neglected
This is why feeding amounts should be adjusted as your dragon matures.
Balancing Live Food with Greens
Bearded dragons should not rely entirely on insects. A balanced diet includes both live feeders and plant matter.
- Juveniles: mostly insects with some greens
- Adults: mostly greens with occasional insects
Greens provide essential vitamins and help prevent dietary imbalances that can occur with an insect-heavy diet.

How to Know You Are Feeding the Right Amount
The best way to judge feeding is by observing your bearded dragon’s condition and behaviour.
- steady growth in juveniles
- healthy weight without excessive fat
- strong feeding response
- consistent energy levels
If your dragon is gaining too much weight, reduce insect intake. If growth is slow in juveniles, increase feeding slightly.
Common Mistakes to Avoid
- feeding roaches that are too large
- overfeeding protein to adult dragons
- not offering enough greens
- feeding inconsistent amounts
