Feeding Hornworms to Bearded Dragons: A Keeper's Complete Guide

I've fed hornworms to bearded dragons for years, and they're one of the most misunderstood feeders in the hobby. Half the care articles online sell them as a "protein-rich superfood," and the other half warn they're "too fatty." Both are wrong, and in nearly opposite directions. The truth is simpler and more useful once you have it: a hornworm is essentially a soft, juicy bag of water with a bit of protein and a decent mineral profile. That makes it a fantastic hydration treat and appetite-stimulant — and a terrible staple. Understand that one fact and every feeding decision in this guide falls into place.

This is the complete, honest version: what hornworms actually are, what's really in them (with the numbers, corrected), why they're a treat and not a meal, how often and how much to feed by life stage, how to size them safely, how to keep them alive on your counter, how to gut-load and present them, the real risks, and how to win over a dragon that turns its nose up. Read it once, set your feeding rhythm, and you'll get all the upside of this feeder with none of the loose-stool, impaction, or malnutrition problems that come from treating it like something it isn't.

What a hornworm actually is

The "hornworm" sold as a feeder is the caterpillar (larval stage) of the tobacco hawk moth, Manduca sexta — sometimes you'll also see the closely related tomato hornworm, Manduca quinquemaculata. They're called hornworms for the soft, curved spike on the tail end (it's harmless), and you'll see them marketed as "Goliath worms" because captive ones grow large and fast. In the wild they're a notorious agricultural pest on tomato and tobacco plants — which, as you'll see in the wild-caught section, is exactly why you never feed the ones in your garden.

A feeder hornworm is bright blue-green, soft-bodied, plump, and constantly moving. That combination — vivid color plus active wriggling — is catnip to a bearded dragon's hunting instinct, which is half of why they're such a useful tool for a picky or off-feed dragon. They arrive small (a quarter-inch to an inch) in a plastic "horn pod" or cup with food gel already in the bottom, and under warm conditions they grow shockingly fast, going from cup-size to three or four inches in a couple of weeks. That growth speed is both their charm and the thing you have to manage, because a worm that's the right size today can be too big to feed safely in five days.

Commercially, hornworms are raised on a sterile artificial diet (a wheat-germ-based gel), not on tomato or tobacco leaves. That's important: the captive diet is what makes them safe. The toxins that make wild hornworms dangerous come from the nightshade plants they eat, and feeder-farm worms never touch those plants.

The nutrition, honestly (and where the internet gets it wrong)

This is the section that matters most, because almost every salesy hornworm article gets it backwards. Let me give you the real numbers and then correct the three myths you'll keep running into.

On a fresh-weight (as-fed) basis, a feeder hornworm is approximately:

• ◆Moisture: ~85% — extremely high. This is the single defining feature of the feeder.
• ◆Protein: ~9% — low, not high. Roughly half what a dubia roach or cricket delivers per worm.
• ◆Fat: ~3% — genuinely low.
• ◆Minerals: a better calcium-to-phosphorus ratio than most feeders, plus useful traces of magnesium, potassium, and some vitamin A — but the absolute calcium amount is still modest, not a substitute for supplementation.

Now the three corrections, because you will read the opposite everywhere:

Myth: "Hornworms are protein-rich." They're not. At ~9% protein they're one of the lowest-protein feeders you can buy. A big part of why they look impressive on a plate is volume — a fat hornworm is large — but most of that bulk is water, not muscle-building protein. If you feed a hornworm-heavy diet to a growing juvenile, you are quietly underfeeding protein while the dragon looks like it's eating plenty. That's the most damaging mistake with this feeder.

Myth: "Hornworms are too fatty." Also false, and notice it directly contradicts the first myth. At ~3% fat they're one of the leanest feeders available — far lighter than waxworms or superworms. You'll even see single articles that call them "low in fat" in one paragraph and "relatively high in fat" in another. They are low-fat. Full stop. (You can usually trace the "fatty" myth to people confusing hornworms with waxworms, which actually are fatty.)

Myth: "Hornworms have a favorable Ca:P ratio, so they cover calcium." This is the half-truth that does real harm. Hornworms genuinely do have a more favorable calcium-to-phosphorus ratio than most feeder insects — most feeders are badly phosphorus-heavy, and hornworms are less so. But "less bad than crickets" is not "a calcium source." The total calcium per worm is still modest, and bearded dragons — especially juveniles and gravid females — have high calcium demands to prevent metabolic bone disease (MBD). So you still gut-load, and you still dust with calcium on the schedule your dragon's life stage calls for. Treating hornworms as your calcium plan is how dragons end up with MBD while their keeper swears they were "feeding lots of calcium-rich hornworms."

The honest one-line summary: hornworms are a high-moisture, low-protein, low-fat, mineral-decent treat. Their job is hydration, variety, and appetite stimulation — not building a body.

What hornworms are genuinely great for

Reframed correctly, hornworms earn a permanent place in the rotation. Here's where they shine:

• ◆Hydration. At ~85% water, a few hornworms are a meaningful water delivery, which matters a lot for a species that often won't drink from a standing dish. They're my go-to in dry months, after a long brumation, for a dragon recovering from illness, or for any dragon that's borderline dehydrated (sunken eyes, wrinkled skin, sticky mouth, infrequent or hard stool). Diet hydration is gentler and more reliable than hoping the dragon drinks.
• ◆Appetite stimulation. That blue-green color and constant wiggle reliably re-trigger the hunt drive in a dragon that's gone off its food. When I have a dragon that's bored of its staple or coming out of a slow patch, a wiggling hornworm on tongs often breaks the strike.
• ◆Soft, easy digestion. No hard chitin shell, no tough head capsule. That makes them safe and easy for hatchlings, seniors, and any dragon recovering from a jaw, mouth, or gut issue — situations where a hard-shelled cricket or superworm is a poor choice.
• ◆Lean treats for chunky adults. Because they're low fat and low calorie-density-per-water, they're a smart treat for an overweight or sedentary adult that can't afford waxworms or superworms.
• ◆Low parasite/disease risk when captive-bred, because of the sterile farmed diet and controlled rearing.

That's a genuinely valuable toolkit — as long as you remember it's a toolkit, not a foundation.

The vitamins and trace minerals — and one real caution

The macros (water, protein, fat) are the headline, but the micronutrients are worth knowing because they explain both why hornworms are useful and where to be careful.

• ◆Calcium is the one people fixate on. As covered above, the calcium-to-phosphorus ratio is better than most feeders, but the absolute amount is still modest — useful as a contribution, not a substitute for dusting. Calcium is what prevents metabolic bone disease, so it's the mineral you never gamble on.
• ◆Vitamin A is present, and this is the one to be slightly cautious about. Vitamin A supports vision, skin, and immune function, but bearded dragons are sensitive to excess preformed vitamin A — too much from any combined source (feeders plus a vitamin-A-heavy multivitamin) can tip into toxicity, which shows up as swelling, skin issues, and lethargy. Hornworms alone won't do this, but it's a reason not to stack a heavy vitamin-A supplement on top of a varied, A-containing diet. Moderation across the whole picture, not just the worm.
• ◆Magnesium appears in trace amounts and works alongside calcium for nerve and muscle function.
• ◆Potassium is present and is part of why hornworms help with hydration and fluid balance — relevant for a dragon in a warm, dry setup.
• ◆Iron shows up in small amounts, supporting oxygen transport in the blood. Hornworms aren't a major iron source, but it rounds out the variety argument.

None of these change the headline — hornworms are a hydration treat — but they're a genuinely nutrient-varied treat, which is more than you can say for, say, waxworms. The variety of trace minerals is a real, if minor, point in their favor.

Hornworms vs. other common feeders

The clearest way to place hornworms is next to the feeders you already use. These are approximate as-fed figures — real values swing with diet, life stage, and supplier — but the relationships are reliable and they're what should drive your choices.

The takeaways that actually change how you feed:

• ◆Hornworms are the hydration specialist, not a protein source. Pair them with a real staple; never make them the meal.
• ◆Roaches (dubia or discoid) are the protein backbone. If you keep a colony, you own the staple cheaply at home — I walk through that in the discoid roach colony playbook and the discoid feeding guide for dragons.
• ◆Superworms are a fatty treat, not interchangeable with hornworms — that ~15% fat adds up fast. See the superworm guide for where they fit.
• ◆The right diet is a staple plus rotated variety: roaches/crickets as the base, hornworms for hydration, BSFL for a calcium nudge, superworms and waxworms as rare treats.

How often to feed hornworms, by life stage

The cardinal rule first: hornworms supplement, they don't replace. A staple feeder and greens come first; hornworms slot in around them. With that fixed, here's the rhythm I use.

Hatchlings and juveniles (0–~12 months)

Young dragons are growth machines that need a lot of protein and calcium daily, which is exactly what hornworms don't provide. So they stay a supplement even here. I offer two or three small-to-medium hornworms two or three times a week, always alongside a protein staple in the same week — never as the protein meal itself. The soft body is a real plus for tiny dragons, but if hornworms crowd out staple insects, growth stalls and you risk MBD. Hydration and variety are the goal; roaches and crickets do the building.

Adults (~12+ months)

Adults shift toward more greens and less protein, and need fewer feeder insects overall. Hornworms become a clear treat here: one to three medium hornworms once or twice a week is plenty. They're especially good for an adult that's overweight (lean treat), reluctant to drink (hydration), or bored of its food (appetite). Don't let an adult eat a big pile of them in one sitting — that's the fast track to watery stool.

Gravid females, recovering, or off-feed dragons

These are the situations where hornworms truly earn their keep. A gravid female burns through calcium — feed her a calcium-rich staple and dusted feeders, but use hornworms for hydration support. For a dragon recovering from illness or coming out of brumation, the soft body and high water content make hornworms one of the gentlest ways to get something nutritious and hydrating in. Still keep portions modest and watch the stool.

A practical warning that flows straight from the nutrition: because hornworms are so palatable, dragons can act "addicted" — refusing staples in hopes of more hornworms. They don't get chemically dependent, but they will hold out for the tastier food if you let them. Keep hornworms a scheduled treat, not an on-demand one, and your dragon keeps eating its actual diet.

Portion size and the size rule that prevents impaction

Two things matter: how many and how big. People obsess over the count and ignore the size, but size is the one that sends dragons to the vet.

The size rule: never feed a hornworm wider than the space between your dragon's eyes. That's the universal feeder rule, and it's especially important here because hornworms grow so fast — a perfectly sized worm becomes an oversized one within days. Too-large prey is the leading cause of choking and gut impaction in bearded dragons. For hatchlings and small juveniles, feed small worms or simply cut a larger hornworm into appropriate pieces (they don't have to be whole to be eaten — a cut worm actually releases scent and often gets a hesitant dragon interested).

The count rule: start small and watch the stool. If droppings go loose and watery, you've overdone it — that's purely the ~85% water, not an illness. Back the portion down. A few hornworms is a treat; a dozen in one sitting is a digestive upset waiting to happen. Calorie- and water-density matter more than the dramatic visual size of the worm.

Put simply: right size every time, modest count, firm stool as your feedback signal.

Using hornworms to fight dehydration

Hydration is the headline use, so it's worth being concrete about when to reach for them and how to tell they're working.

Bearded dragons evolved in arid Australia and are built to extract water from food, which is exactly why many of them ignore a standing water dish entirely. That's fine when the diet carries moisture, but in a dry home, a hot-running basking setup, or a winter with the heat on, a dragon can slide into mild chronic dehydration without an obvious moment of crisis. Left unaddressed, dehydration contributes to constipation and impaction, and over time stresses the kidneys.

The signs I watch for:

• ◆Sunken or dull eyes, sometimes with wrinkled skin around them.
• ◆Skin that's slow to flatten when gently pinched (loose, "tented" skin).
• ◆Wrinkled, loose, or leathery skin generally, and dull rather than vivid color.
• ◆Sticky, stringy saliva or a dry mouth.
• ◆Infrequent, hard, or dry stool, or straining to pass it.
• ◆Lethargy and reduced appetite in worse cases.

This is where a few hornworms shine. Because they're ~85% water, two or three of them deliver a meaningful, gentle dose of fluid through food — far more reliable than hoping the dragon drinks. I lean on them during dry months, after brumation (when a dragon is rehydrating and rebuilding appetite at once), and for any dragon trending dry. Pair the hornworms with the usual hydration tools — a shallow water dish, light misting, the occasional lukewarm soak — and you cover the gap from several directions. Just don't overcorrect: a sudden pile of hornworms swings you straight to watery stool. A few, consistently, beats a feast.

Choosing quality hornworms

You can't gut-load your way out of starting with bad worms. Here's what I check before feeding.

Visual signs of a healthy worm

• ◆Color: bright, vivid blue-green. Faded, pale, gray, or blackened worms are stressed, sick, or dying — don't feed them.
• ◆Movement: active and responsive. Lethargic or limp worms are on their way out.
• ◆Body condition: plump and firm, not shriveled (dehydrated/starved) or mushy (rotting). A worm that's gone soft and dark or smells off goes in the trash, not the dragon.
• ◆Size: match it to your dragon now, and remember they grow — buy a size you can use up before they outgrow safe feeding.

Source and handling

• ◆Buy captive-bred from a reputable feeder supplier. This is the single most important quality control — it guarantees the clean farmed diet and controlled rearing that make hornworms safe. When I need them, All Angles Creatures stocks healthy, captive-bred hornworms raised on the proper gel diet and sized for feeding. Good suppliers ship them in vented pods with food already in the cup.
• ◆Inspect the packaging on arrival: it should be vented (to prevent condensation and mold) and the worms should be active. Damaged, soggy, or moldy packaging is a bad sign.
• ◆Free of pesticides/contaminants — another reason to buy farmed rather than collect wild.

Avoiding wild-caught hornworms — this one's non-negotiable

It's tempting: you find fat green hornworms on your tomato plants and think "free feeders." Don't. Wild hornworms are genuinely dangerous to a bearded dragon, for several stacking reasons.

• ◆Plant toxins. Wild hornworms feed on tomato, tobacco, and other nightshades and concentrate the plants' toxic compounds in their bodies. Those toxins can be harmful — potentially lethal — to a small reptile. This is the big one, and it's the real reason behind the "hornworms are toxic" myth: wild ones can be, farmed ones aren't.
• ◆Pesticides and herbicides. Garden and crop plants are frequently treated with chemicals that accumulate in the insects feeding on them, and those go straight into your dragon.
• ◆Parasites and pathogens. Wild insects aren't raised in clean conditions and can carry parasites or disease that are hard to diagnose and treat once introduced.
• ◆Unknown identity and nutrition. Even setting toxins aside, you can't be sure what species you've got or what it's been eating, so the nutrition is a gamble.

The myth to nail down here: commercially raised hornworms are safe; wild ones are not. The difference is entirely the diet they were raised on. Only feed captive-bred worms from a known source.

Keeping hornworms alive on your counter

Hornworms are easy to keep for the short window you need them, if you respect two things: they grow fast at room temperature, and they hate condensation. Here's the routine.

Housing

Leave them in the vented horn pod or cup they shipped in — those come with the food gel in the bottom and proper air holes, and they're designed for exactly this. The cup is typically stored upside down so the worms hang from the mesh lid and their frass (droppings) drops away from them, keeping them clean. If you must move them, use a clean, dry, well-ventilated container; the enemy is trapped moisture, which breeds mold and bacteria fast.

Food

Hornworms eat a commercial wheat-germ-based hornworm gel diet — usually the gel already in the cup. Don't feed them random produce or leaves; the wrong food can throw off their nutrition or, worse, expose them to the very toxins you're avoiding. If they run low on gel and you want them to keep growing, you buy more of the same commercial diet. (Brief gut-loading on greens right before feeding is a different, intentional step — see below.)

Temperature is your growth dial

This is the lever that controls everything:

• ◆To slow growth and extend their usable life: store them cooler, around 50–60°F. This is how you stretch a cup of small worms over a couple of weeks instead of having them all balloon at once. A wine fridge or the warmest part of a regular fridge works; don't let them freeze.
• ◆To grow them fast: keep them at room temperature, ~70–85°F, and they'll size up in days.
• ◆Never overheat them. Extreme heat kills them quickly and turns a cup into mush.

Daily check

Glance at them daily. Pull and discard any worm that's discolored, blackened, mushy, or smells foul, and toss the whole cup if you see mold in the gel — one rotting worm or a mold bloom can take the rest down. Healthy worms are green, plump, and moving.

Gut-loading and preparing hornworms to feed

Even though hornworms aren't a protein powerhouse, a little prep makes the ones you feed meaningfully better.

1. ◆Inspect. Only feed bright, active, plump worms. Skip anything sluggish, discolored, blackened, or soft.
2. ◆Size it. Confirm it's no wider than the gap between the dragon's eyes; cut larger worms into pieces for small dragons.
3. ◆Gut-load (24–48 hours). Before feeding, let the worms eat nutrient-dense dark leafy greens (collard, mustard, dandelion) or a commercial gut-load. Whatever's in the worm's gut is in your dragon a step later, so this is a cheap way to upgrade an otherwise watery feeder. Don't gut-load on anything toxic or pesticide-exposed.
4. ◆Rinse, optionally. A gentle rinse in clean water and a pat dry adds a small margin against any surface residue. Captive worms are clean to begin with, so this is a precaution, not a requirement.
5. ◆Present with tongs. Offer one worm at a time with soft-tipped feeding tongs. Tongs keep your fingers clear of an accidental bite, let you wiggle the worm to trigger the strike, and stop the dragon from lunging at substrate (a loose impaction risk). Feed in the enclosure or a clean feeding bin, and remove anything uneaten.

Real risks and how to avoid them

Hornworms are one of the safer feeders, but a few specific things will bite you if you ignore them.

• ◆Loose / watery stool from overfeeding. The most common issue, and it's purely the high moisture. Fix: smaller portions, spaced out. Not a disease.
• ◆Impaction or choking from oversized worms. The most serious issue. Fix: the eye-width size rule, every time, no exceptions — and remember they grow fast, so re-check size each feeding.
• ◆Malnutrition from over-reliance. The most insidious issue, because the dragon looks well-fed while getting too little protein and calcium. Fix: keep hornworms a supplement; build the diet on a staple. This is the trap baked into the "protein-rich superfood" myth.
• ◆Toxins/pesticides/parasites from wild worms. Fully avoidable. Fix: captive-bred only.
• ◆Picky-eater dependence. Dragons may hold out for hornworms and snub staples. Fix: scheduled treat, not on demand.
• ◆Rare sensitivities. Genuinely uncommon, but if you ever see lethargy, swelling, persistent diarrhea, or odd color changes after feeding, stop the worms and consult a reptile-experienced vet. Keeping a simple feeding log makes it easy to spot a real pattern versus a one-off.

For anything health-related beyond ordinary loose stool — suspected impaction, MBD signs, persistent refusal to eat — a reptile vet is the right call. The Merck Veterinary Manual's bearded dragon nutrition reference is a solid, non-commercial overview of reptile dietary needs, and your nearest university veterinary or extension program (for example, the University of Florida's herpetology and wildlife resources) is a reliable place to confirm species-appropriate care.

Can you raise hornworms at home?

Short answer: you can grow them out, but breeding a self-sustaining supply is more project than most keepers want. Here's the honest version.

Growing out the ones you buy is genuinely easy and worth doing. If you buy small worms and keep them at room temperature with enough commercial gel diet, they'll size up fast — that's just managing the temperature dial described above. Buy small, grow to the size you need, slow them down in the cold if they're getting ahead of you. That alone gets most people everything they want.

Actually breeding them is a different commitment. Hornworms are a larval stage — feed them up and they'll stop eating, burrow (they want a substrate to pupate in), and pupate into tobacco hawk moths. The moths then need space to emerge, harden, and fly to mate, plus a flight enclosure and a way to collect eggs, and the larvae need a continuous supply of artificial diet (or, in the wild, nightshade leaves you specifically don't want in a feeder). It's doable for a dedicated hobbyist but it's a real undertaking with equipment and timing demands — not the low-effort home colony that, say, a roach bin is.

My recommendation for almost everyone: buy captive-bred worms as you need them and grow them out, rather than trying to close the breeding loop. The cost-per-treat is low, the worms arrive clean and safe, and you skip the moth-husbandry rabbit hole. If you want a feeder you breed cheaply at home, put that energy into a roach colony — that's the staple anyway — and let hornworms stay the bought-in treat. Their short usable life (they grow out of feeding size quickly and don't store for months the way a roach does) is the one real downside to plan around: buy quantities you'll actually use, and use the fridge to stretch them.

Reading your dragon: signs the diet is working

Hornworms are a tool inside a bigger diet, so the real test isn't the worm — it's the dragon. When the overall diet (staple + greens + supplements + treats like hornworms) is right, a bearded dragon shows it clearly. These are the markers I check, and they're how you catch a problem — including over-reliance on hornworms — before it becomes serious.

Body and appearance

• ◆Healthy weight and proportions. Well-filled body, no visible ribs or sharply protruding spine, but no rolls of fat at the limbs or a bloated belly either. A dragon eating too many hornworms can look fine on weight while being protein-short, so weight alone isn't the whole story.
• ◆Bright, smooth skin. Vivid color and clean, even scales between sheds — not persistently dull, flaky, or discolored.
• ◆Clear, full eyes. Bright and alert, not sunken (dehydration) or cloudy.

Behavior

• ◆Active and alert. A well-nourished dragon basks, explores, and hunts with energy.
• ◆Steady, broad appetite. It eats enthusiastically across the menu — not just the hornworms. A dragon that strikes hard at hornworms but snubs its staple is telling you the treat has become a crutch.

Digestion

• ◆Regular, well-formed stool. Firm and consistent is the goal. Watery stool right after a hornworm session usually just means too many worms; persistent loose stool, or constipation, means it's time to reassess portions and overall balance.

If those markers are good, your rotation — hornworms included — is working. If one drifts, the diet is the first place to look, and hornworm portion size is one of the easiest things to adjust.

Tracking weight when you add hornworms

Any diet change deserves a little measurement, and hornworms are no exception. I weigh dragons on a digital kitchen scale accurate to the gram, on the same schedule (say, weekly, at the same time of day), and jot it down. The point isn't to chase a number — it's to catch a trend.

• ◆Steady, age-appropriate growth or a stable adult weight means the rotation is balanced.
• ◆Stalled growth in a juvenile despite "lots of food" is a classic sign hornworms (or other low-protein treats) are crowding out the staple. The dragon's eating volume, not nutrition. Shift the balance back toward roaches and crickets.
• ◆Creeping weight gain in an adult points to too many calorie-dense treats overall — though hornworms are rarely the culprit there, given how lean they are. Look at superworms and waxworms first.

Pair the scale with the health markers above and a simple feeding log (what, how much, when), and you'll always know whether a change helped. A reptile-experienced vet check once or twice a year backs all of this up, especially for growing juveniles and breeding females.

Introducing hornworms to a hesitant dragon

Plenty of dragons inhale their first hornworm. Some balk at the unfamiliar texture, color, and movement — that's normal, not a problem with the worm. Here's how I win them over.

• ◆One at a time. Offer a single worm and read the interest level before adding more.
• ◆Wiggle it on tongs. The motion mimics live prey and triggers the strike reflex; hornworms' own wriggling helps too.
• ◆Time it right. Feed when the dragon is warm and hungry — after it's basked up to temperature, often mid-morning. A cold dragon won't hunt.
• ◆Cut it. For small or very hesitant dragons, cutting a worm makes it less intimidating and releases scent.
• ◆Mix it in. Offer hornworms alongside a familiar feeder (a roach or cricket) so the new food shows up in a trusted context.
• ◆Keep it calm. A quiet, low-stress feeding environment matters; a stressed dragon won't eat. Don't loom or make sudden moves.

Patience wins. Most dragons accept hornworms within a few tries, and many then love them — which loops you right back to the "scheduled treat, not on demand" rule.

Where hornworms fit in the whole diet

Zoom out and the picture is simple. A healthy bearded dragon diet is built from:

• ◆A staple protein source — dubia or discoid roaches, crickets — sized and dusted, fed daily to juveniles and a few times a week to adults.
• ◆Fresh greens and veg — collard, mustard, and dandelion greens, squash, bell pepper — the calcium-rich, fiber-rich base, and the larger share of an adult's plate.
• ◆Calcium and vitamin supplementation — calcium dust (with or without D3 per your lighting), and a multivitamin on schedule, because no feeder fully covers a dragon's calcium needs.
• ◆Rotated variety and treats — hornworms for hydration and appetite, BSFL for a calcium nudge, superworms and waxworms rarely.

Hornworms are one valuable instrument in that ensemble: the hydration-and-appetite specialist. Use them for that, two or three times a week at most, sized correctly and gut-loaded, and they're an excellent, safe, genuinely useful feeder. Ask them to be the meal, and they'll quietly let a dragon down. Keep them in their lane and they'll keep your dragon hydrated, interested in food, and thriving.

The short version

Hornworms are ~85% water, ~9% protein, ~3% fat with a decent-but-not-sufficient mineral profile — a hydration and appetite treat, not a staple. Feed captive-bred worms only; size them no wider than the dragon's eyes (they grow fast — re-check every time); offer two or three to a juvenile two or three times a week, one to three to an adult once or twice a week; gut-load on greens for a day before feeding and dust with calcium per life stage; store cool to slow growth; and watch the stool — loose means cut the portion. Do that and you get all the upside with none of the trouble.
