Red-Eyed Crocodile Skink Care Guide: Don’t Risk It

As reptile enthusiasts transitioning from geckos to more delicate species, red-eyed crocodile skinks (Tribolonotus gracilis) are enchanting—but also notoriously sensitive. With lifespans of up to 10 years, they demand meticulous care. Neglect key factors—humidity, temperature, and lighting—and you could face catastrophic illness, or worse.

1. Enclosure Essentials: Perfect Size, No Compromises

Minimum size: For a single adult, aim for a 24″ × 18″ × 18″ (60 × 45 × 45 cm) or larger. Bigger is better. Some experts recommend 90 × 45 × 45 cm for more roaming space.
Housing solo or in pairs: These skinks are generally territorial, but compatible pairs can coexist peacefully. Monitor closely for signs of stress or aggression.
Deep substrate: 3–4” of moisture-retentive bedding like coconut fiber, eco earth, and leaf litter helps maintain humidity and allows burrowing behavior.

2. Humidity & Hydration: Stay Above 70% — Every Day

Daily RH: 70–80%; Night: 80–100%.
Tools: Digital hygrometer, misting bottle, fogger or humidifier, and use only RO or distilled water.
Water dish: Medium shallow bowl permitting partial soaking — clean it weekly with vet-safe cleaner.

Why it matters: Skinks are prone to respiratory infections and dehydration—a slight drop and they begin to decline.

3. Temperature & Lighting: Tropical Comfort

Warm hide: 80–82 °F (27–28°C); Cool zone: 75–78 °F (24–26°C); Night: not below 72 °F (22°C).
Heat source: Use a 50–60 W white heat lamp in a dimmable dome.
Night-time: The Ceramic heat emitter is ideal if your room dips lower.
Lighting:
- Provide a 12‑hour cycle of full-spectrum light.
- UVB: Not mandatory if supplementing D3, but highly recommended. Use T5 high-output 6% bulbs positioned 8–14″ above the terrarium.
- Replace bulbs every 12 months.

Insider Tip: Use a combined Thermo-Hygro probe inside the hide and across zones to monitor gradients.

4. Diet & Supplements: Balance or Bust

Feeding schedule: Juveniles daily, adults every other day. Offer insects about half the head size, limited to a 5‑minute feeding window.
Insect variety: Crickets, dubia roaches, discoid roaches, BSF larvae, mealworms, superworms, silkworms, hornworms, earthworms, canned snails.
Dubia advantage: Cleaner, less odor, more nutritious
Supplements: Dust feeders with calcium at every feeding, plus multivitamins twice a week.

Customer Sarah lost her female skink to metabolic bone disease before switching to the right supplement. Eight months later, it’s thriving and more active than ever.

5. Décor & Enrichment: Hide More, Stress Less

Skinks aren’t show-offs—they’re shy. Offer plenty of hides and climbing branches to reduce stress.

Must-haves:

Two hides (warm zone, cool zone) – Try our Gecko Place, made from eco-friendly PLA plastic that’s safe for your pet and the planet. Its curved shape provides comfort, support during shedding, and a cool perch on top.
Cork flats/tubes & natural branches – For climbing and cover.
Geckopia Dig Box – A cozy, light-blocking hide designed for digging and de-stressing. Great for capturing adorable gecko moments, too.
Live plants and moss (bioactive)
Water feature – Add a shallow stream or dish to maintain humidity.

6. Handling & Bonding: Patience Over Force

Not a pet to handle often — they stress easily, vocalize, drop tails, and play dead when handled.
Hand-feeding via tongs after 2 weeks of settling helps build trust.
Monthly health checks: Inspect skin, appetite, feces, and weight. A reddening under the eyes? It could be an early infection.

Case Study: Emily reported, “Within 3 months of the switch, feeding by hand, my skink eats readily from tongs and even follows me near the glass!”

7. Common Issues & Solutions

Problem	Possible Cause	Solution
Dry cracked skin	Low humidity	Increase misting, add fogger
Lethargy/loss of appetite	Temperature is too low or MBD	Check temps, add supplements
Bacterial/fungal issues	Dirty substrate or water bowl	Spot clean daily, full substrate change 3‑4 months
