Veiled chameleons are insectivorous hunters that use their projectile tongues to capture prey. Proper nutrition requires exceptional insect variety (10+ types), careful supplementation sensitive to chameleon needs, and gutloading protocols. This guide covers feeding schedules, acceptable feeders, supplementation (Arcadia EarthPro A + Repashy LoD), and feeding techniques.
Chameleons Are Supplement-Sensitive: Unlike bearded dragons or leopard geckos that tolerate over-supplementation, chameleons develop hypervitaminosis (vitamin toxicity) and kidney failure from excessive vitamins. Use supplements SPARINGLY - Arcadia EarthPro A every feeding (light dust), Repashy Calcium Plus LoD or Arcadia Revitalise D3 only 2x per month. NEVER use daily multivitamins or standard calcium + D3 powders marketed for other reptiles.
| Age/Size | Feeding Frequency | Insects Per Feeding | Insect Size | Notes |
|---|---|---|---|---|
| Hatchlings (0-3 months, 0-10g) | Daily, as much as they'll eat | 10-20 small insects | 1/4" crickets, fruit flies, pinhead roaches | Rapid growth phase - prioritize quantity and calcium. Dust every feeding with Arcadia EarthPro A |
| Juveniles (3-8 months, 10-50g) | Daily | 8-15 appropriately-sized insects | 1/2" crickets, small dubias, small hornworms | Still growing - daily feeding essential. Begin diet variety rotation (3-4 feeder types weekly) |
| Sub-Adults (8-12 months, 50-100g) | Daily tapering to every other day | 5-10 insects | 3/4" crickets, medium dubias, medium hornworms | Transition period - reduce frequency gradually. Males continue growing; females may start egg production |
| Adult Males (12+ months, 100-180g) | Every other day | 4-5 large insects | Adult crickets, adult dubias, large hornworms, locusts | Established metabolism. Feed every 48 hours. Adjust if weight loss/gain occurs |
| Adult Females (12+ months, 80-120g) | Every other day, increase during egg production | 4-5 medium-large insects | 3/4" crickets, adult dubias, medium hornworms | Females produce eggs without mating - require extra calcium during follicle development. Monitor body condition closely |
Feeding Time Matters: Offer insects mid-morning (9-11 AM) after 2-3 hour basking period when metabolically active. Chameleons have slow digestion requiring warmth - feeding late afternoon means undigested food overnight at cooler temps. Never feed after lights out.
ReptiFiles lists these feeders as safe for veiled chameleons. Variety is CRITICAL - rotating 5-7 types prevents nutritional deficiencies and maintains feeding interest.
| Feeder Type | Nutritional Value | Feeding Frequency | Notes |
|---|---|---|---|
| Crickets (Acheta domesticus) | Moderate protein, low fat, good calcium:phosphorus | Staple - can offer 2-3x/week | Most common feeder. Noisy, short lifespan (3-4 weeks). Gutload heavily 48 hours before feeding |
| Dubia Roaches | High protein, moderate fat, excellent calcium ratio | Staple - 2-3x/week | Quiet, long lifespan (12+ months), easy gutloading. Illegal in FL/HI. Slower movement (less stimulating) |
| Black Soldier Fly Larvae (BSFL) | Moderate protein, HIGH calcium (ideal Ca:P ratio) | 2-3x/week - excellent calcium source | Self-gut-loading (don't require feeding). Low activity = less enrichment. Great for gravid females |
| Blue Bottle Flies & Larvae | Low-moderate protein, high activity | 1-2x/week - enrichment feeder | Excellent flight simulation for tongue practice. Larvae ("spikes") easier to contain than adult flies |
| Hornworms | Low protein, very high moisture (85% water) | 1-2x/week as hydration treat | Fast-growing (too large quickly). High phosphorus - balance with high-calcium feeders. Bright green = easy to see |
| Silkworms | High protein, good calcium, low fat | 2-3x/week - excellent staple | Nutritious and safe. Require fresh mulberry leaves or commercial chow. Short shelf life (7-10 days) |
| Locusts | High protein, low-moderate fat | 1-2x/week - variety/enrichment | Active hoppers trigger strong hunting response. Larger size good for adult chameleons. Expensive ($1-2 each) |
| Red Runner Roaches | High protein, very active | 1-2x/week | VERY fast - use feeding cup to prevent escapes. Legal everywhere unlike dubias. Excellent enrichment |
| Stick Insects (Phasmids) | Low-moderate protein | Occasional (1-2x/month) | Slow-moving, odd shape provides novelty. NOT a staple - supplemental variety only |
| Snails (Captive-Bred) | Moderate protein, HIGH calcium (shell) | 1-2x/month | Crush shell slightly to encourage eating shell (calcium). Never wild-caught (pesticide risk) |
| Mantis Hatchlings | High protein, low fat | Occasional (1x/month) | Novelty feeder. Small size only suitable for juveniles. Avoid adult mantis (too large, aggressive) |
AVOID These Insects: NEVER feed wild-caught insects (pesticide/parasite risk), fireflies/lightning bugs (highly toxic - deadly), king mealworms for juveniles (impaction risk), boxelder bugs (toxic), or monarch butterflies (toxins from milkweed diet). Also avoid superworms and mealworms as staples - high chitin (indigestible exoskeleton), poor nutrition, cause impaction.
- Golden Rule: Insect length should NOT exceed distance between chameleon's eyes. Oversized feeders = choking risk, refusal to eat, stress
- Hatchlings (0-3 months): 1/4 inch crickets (pinheads), fruit flies (Drosophila hydei), pinhead dubias, BSFL (small)
- Juveniles (3-8 months): 1/2 inch crickets, small dubia nymphs (1/4-3/8"), small hornworms (1-1.5")
- Sub-Adults (8-12 months): 3/4 inch crickets, medium dubias (1/2-5/8"), medium hornworms (2-2.5"), small locusts
- Adults (12+ months): Adult crickets (1 inch), adult dubias (3/4-1"), large hornworms (3-4"), adult locusts (2-3")
Gutloading is feeding insects high-quality nutrition 48-72 hours before offering to chameleon. "You are what your feeders eat" - proper gutloading transfers vitamins/minerals to chameleon.
Commercial Gutload Products (Easiest):
- Repashy Bug Burger ($12-15 for 12oz) - Complete gel diet, add water, lasts 5-7 days refrigerated
- Arcadia Insect Fuel ($15-18 for 120g) - Powder form, mix with water into paste
- Cricket Crack ($10-12 for 8oz) - Dry powder, sprinkle over vegetables
- Fluker's High-Calcium Cricket Diet ($8-10) - Affordable option, less comprehensive nutrition
DIY Gutload (Budget Option):
- Best Vegetables: Collard greens, mustard greens, dandelion greens, squash, sweet potato, carrots (grated), bell peppers
- Fruits (10-20% max): Mango, papaya, berries - small amounts for palatability
- Add-Ins: Bee pollen (1 tsp per cup vegetables), spirulina powder (1/2 tsp), fish flakes (1 tbsp)
- Avoid: Iceberg lettuce (zero nutrition), spinach (binds calcium), tomatoes (acidic), onion/garlic (toxic), avocado (toxic)
- Preparation: Chop finely, mix thoroughly, offer to insects in shallow dish. Replace every 24 hours (molds quickly)
Gutloading Timeline:
- Minimum 48 hours before feeding: Begin offering gutload to feeder insects
- 72+ hours ideal: Allows complete digestive tract filling with nutrition
- Continuous gutloading: Keep insects on high-quality diet constantly (not just before feeding). Healthy insects = better nutrition for chameleon
- Hydration: Provide water crystals or fresh vegetables for insect hydration. Dehydrated insects = poor nutrition transfer
Chameleons are highly sensitive to vitamin toxicity. ReptiFiles recommends conservative supplementation with Arcadia EarthPro A (contains bee pollen) and minimal D3.
| Supplement | Frequency | Application Method | Notes |
|---|---|---|---|
| Arcadia EarthPro A | EVERY feeding | Light dusting - insects should look lightly powdered (not caked) | Primary supplement. Contains calcium, trace minerals, bee pollen. NO vitamin D3 (chameleon synthesizes from UVB). Suitable for daily use |
| Arcadia Revitalise D3 OR Repashy Calcium Plus LoD | 2x per month only | Light dusting - very thin coating | Low-dose D3 + vitamins. Use 1st and 15th of month. LoD = Low D3. NEVER use more frequently - chameleons sensitive to D3 overdose (causes kidney failure) |
| Multivitamin (Herptivite, ReptiVite) | AVOID - NOT RECOMMENDED | N/A | Standard reptile multivitamins too strong for chameleons. Stick to Arcadia/Repashy chameleon-specific formulas only |
Dusting Technique:
- Place 5-10 insects in plastic container or ziplock bag with 1/4 teaspoon Arcadia EarthPro A
- Shake/tumble gently for 10-15 seconds until insects lightly coated
- Insects should still be visible through powder - NOT thick breading. Over-dusting causes refusal to eat
- Offer immediately - powder wears off as insects groom within 15-20 minutes
- On D3 days (2x month): Dust half the insects with EarthPro A, half with Arcadia Revitalise D3/Repashy LoD. This prevents excessive D3 if chameleon eats all feeders
D3 Toxicity Warning: Chameleons with UVB lighting synthesize vitamin D3 naturally. Additional D3 supplementation should be MINIMAL (2x monthly only with low-D3 formulas). Daily D3 supplementation or using standard calcium + D3 powders causes hypervitaminosis D3: symptoms include lethargy, organ calcification, kidney failure, death. If chameleon shows neurological signs (twitching, seizures, loss of coordination) after supplementation, STOP all supplements immediately and consult exotic vet.
Free-Roaming (Best for Behavioral Enrichment):
- Release insects directly into enclosure - triggers natural hunting behavior
- Best for: Crickets, dubias, locusts (active crawlers/jumpers)
- Pros: Maximum enrichment, exercises tongue projection, natural behavior
- Cons: Difficult to track intake, insects may hide/escape enclosure, crickets can nibble sleeping chameleon
- Best practice: Release insects in morning, observe feeding for 15-20 min, remove uneaten insects after 2-3 hours
Feeder Cup (Better Control):
- Mount transparent plastic cup or deli container at mid-height (18-24" high). Chameleon can see insects moving inside
- Best for: Dubias, BSFL, hornworms, silkworms (slower crawlers)
- Pros: Accurate intake tracking, prevents escapes, easy supplement application
- Cons: Less natural, requires training chameleon to recognize cup as food source (2-5 days)
- Setup: 16-32oz deli cup with smooth sides (insects can't climb out easily). Secure with zip ties mid-level on mesh wall
Tong Feeding (Training/Bonding):
- Hold insect with 6-10" feeding tongs, present at chameleon eye level 6-12" away
- Best for: Large feeders (hornworms, locusts), training, building trust
- Pros: Bonds chameleon to keeper, precise intake control, works for picky eaters
- Cons: Time-intensive, some chameleons wary of tongs, requires slow movements
- Technique: Hold insect still or wiggle slightly to trigger prey drive. Wait patiently 30-60 seconds for tongue strike
Feeding Method Recommendation: Combine approaches for best results. Use feeder cup for daily base diet (easy tracking) + occasional free-roaming feeders (enrichment) + hand/tong feeding for treats (bonding). Vary methods weekly to prevent boredom.
ReptiFiles notes veiled chameleons occasionally munch on live plants - thought to aid digestion rather than reflecting true herbivory. While not a dietary requirement, plant matter can supplement hydration and fiber.
- Why They Eat Plants: Digestive aid (fiber), boredom, exploration, hydration supplement. More common in males than females
- How Much: Typically 5-10% of diet or less. Some chameleons never eat plants; others nibble weekly
- Safe Plants: Pothos, hibiscus, ficus benjamina, umbrella plant, wandering jew, money tree, weeping fig, ZZ plant (per ReptiFiles list)
- Not Required: Unlike iguanas or uromastyx, veiled chameleons do NOT need plant matter for survival. Insect diet provides complete nutrition
- Monitor Intake: Excessive plant eating (>20% diet) may indicate nutritional deficiency or illness. Consult vet if dramatic increase in plant consumption
| Problem | Possible Causes | Solutions |
|---|---|---|
| Refusing food 3-5 days | Overfed recently, temperatures too low, stress, illness, gravid female (egg development) | Check basking temp (should reach 85F), reduce handling, skip 2-3 feedings, offer different insect type, inspect for gravid swelling (females) |
| Refusing food 7+ days | Illness (parasites, respiratory infection, MBD), severe stress, enclosure issues | EXOTIC VET immediately. Check all husbandry parameters (temps, humidity, UVB), inspect for symptoms (sunken eyes, lethargy, gaping, discharge) |
| Tongue projection weak/missing prey | Vitamin A deficiency, injury, dehydration, metabolic bone disease | Increase vitamin supplementation (Arcadia Revitalise D3 2x/month), vet exam for injuries, check hydration (skin turgor test), assess UVB exposure |
| Only eating one insect type | Preference developed, insuffient variety exposure | Withholding favorites temporarily (3-5 days), introduce new feeders via tong feeding (more enticing), mix insect types in feeder cup |
| Weight loss despite eating | Parasites (coccidia, pinworms), insufficient feeding frequency, poor supplement schedule | Fecal parasite test by exotic vet, increase feeding frequency to daily temporarily, dust EVERY feeding with EarthPro A, weigh weekly to track |
| Obesity (thick fatty deposits near limbs/tail) | Overfeeding, high-fat feeders (hornworms, superworms), insufficient activity | Reduce feeding to every 3 days temporarily, eliminate high-fat feeders, offer only 3-4 insects per feeding, increase enclosure complexity for activity |
| Choking on large feeder | Insect size too large (exceeds eye-to-eye distance) | Offer smaller insects only (see size chart). If choking occurs: DO NOT intervene physically. Monitor closely - most chameleons can expel or swallow with time. Vet if distress continues 10+ minutes |
| Eating substrate/rocks | Calcium deficiency (pica behavior), boredom, instinct | Cover all substrate with river rocks (prevents access), increase calcium dusting frequency, offer cuttlebone or calcium block, vet exam for deficiencies |
Feeding Success Summary: Variety is KEY - rotate 5-7 insect types weekly. Juveniles eat daily, adults every other day (4-5 insects). Gutload all feeders 48-72 hours. Dust every feeding with Arcadia EarthPro A. Add Arcadia Revitalise D3 or Repashy LoD 2x/month only. Feed mid-morning (9-11 AM) after basking. Use feeder cup + occasional free-roaming for enrichment. Never use standard reptile multivitamins or daily D3 - chameleons sensitive to toxicity.
