Okay, let's talk about the red eyed alligator skink. Seriously cool reptile, right? That name alone – red eyed alligator skink – conjures up images of some miniature prehistoric beast. And honestly, looking at one, it's not far off. Those bony scales, the ridged back, and those piercing red eyes... they're unlike almost anything else in the hobby. I remember the first time I saw one at a reptile expo years ago. It was tucked away in a small tub, looking more like a weird bumpy rock than a lizard until it blinked those startling red eyes. I was hooked.
But here's the thing everyone wants to know upfront: Are they good pets? Well, that depends entirely on what you're looking for. If you want a lizard to handle daily, show off to friends, or watch zip around a huge enclosure, you might be disappointed. The red eyed crocodile skink (another common name, same awesome lizard) is more of a 'look, don't touch' gem. They're shy, they stress easily, and honestly, they spend a LOT of time hiding. But if you're fascinated by unique, prehistoric-looking creatures and appreciate observing natural behaviors (like swimming!), they are utterly captivating. Some folks find their almost stoic stillness boring; I find it incredibly calming and zen.
The Real Deal on Red Eyed Alligator Skink Care (No Sugarcoating)
Alright, let's cut to the chase. Keeping a red eyed alligator skink (Tribolonotus gracilis - science name, good to know) thriving requires getting their environment spot on. They're not *difficult* per se, but they are sensitive. Mess up the humidity or temperature consistently, and you'll run into problems fast.
Setting Up Shop: The Non-Negotiable Tank Requirements
Think rainforest floor. Think damp, warm, and cluttered. Your **red eyed alligator skink** isn't basking on a sunny rock like a bearded dragon. It's scurrying through leaf litter near a stream in New Guinea. We gotta replicate that vibe.
- Tank Size: Forget those tiny critter keepers. Minimum for ONE ADULT is a 20-gallon long tank (30" x 12" x 12"). Bigger is ALWAYS better, especially floor space. Height matters less. I started mine in a 20L and upgraded to a 40-gallon breeder (36” x 18” x 16”) – the difference in their confidence was noticeable.
- Substrate: This is CRITICAL. It needs to hold moisture without being soggy. My go-to mix is:
- 60% Organic Topsoil (NO fertilizers or additives! Seriously, check twice.)
- 30% Coconut Fiber (Coco Coir)
- 10% Play Sand OR Fine Orchid Bark
- Hiding Spots GALORE: These guys are masters of camouflage and stress easily. You need multiple hides that feel secure. Think:
- Cork bark rounds (half-buried look awesome)
- PVC pipes buried in substrate (cheap and effective)
- Commercial reptile caves
- Dense clusters of fake or live plants (Pothos is a hardy winner)
- Leaf litter on top (magnolia, oak, sea grape - pesticide-free!)
- The Water Feature: This isn't optional. Red eyed crocodile skinks LOVE to soak and swim. They are surprisingly aquatic! Provide a large, shallow water dish. I mean LARGE enough for the skink to fully submerge its body. Shallow enough that it can easily climb out (drowning is a risk). Think heavy ceramic dish to prevent tipping. Change that water DAILY without fail. This is their main drinking source and humidity hub.
Heating & Humidity: Getting the Numbers Right
This is where most failures happen. Get a good digital thermometer/hygrometer combo (like ZooMed or Exo Terra). Don't rely on those cheap analog stick-on ones – they're notoriously inaccurate.
Parameter | Daytime Range | Nighttime Range | How to Achieve |
---|---|---|---|
Temperature | 75-80°F (24-27°C) Ambient Avoid hot basking spots! |
70-75°F (21-24°C) | Low-wattage ceramic heat emitter (CHE) or deep heat projector (DHP) on a thermostat. Place OVER tank, not inside. UNDERTANK HEATERS ARE USELESS - heat doesn't penetrate deep substrate. Thermostat is MANDATORY to prevent overheating. |
Humidity | 70-90% CONSTANTLY | Deep moist substrate, large water dish, daily misting (sometimes 2x/day), possibly a glass/acrylic tank lid (covered mostly with plastic wrap or foil if mesh). Automatic misters can help but increase mold risk - ventilation is key too! |
Listen, low humidity is the fast track to a dehydrated, sick skink. Their skin isn't like a gecko's; they need that moisture. But stagnant, swampy air is bad too – aim for damp, not wet. If you see condensation constantly dripping down the glass, you might need *slightly* more ventilation.
Lighting: Keeping it Simple
No fancy UVB debates here! Good news: red eyed alligator skinks are generally considered crepuscular (active at dawn/dusk) and don't have high UVB requirements like basking lizards. A simple low-output UVB bulb (like a 5.0 or Arcadia ShadeDweller) covering part of the tank for 10-12 hours a day is beneficial but not strictly mandatory if diet is supplemented well. I use one because why not offer the option? But the crucial thing is NO bright, hot basking lights. They hate it and will hide even more. Ambient room light often suffices, but a low-level LED plant light or basic overhead lamp on a timer helps regulate their day/night cycle.
Feeding Your Miniature Alligator: Diet & Nutrition
Compared to setup, feeding these guys is relatively straightforward. They're insectivores. Think variety is key!
- Staples: Gut-loaded crickets, dubia roaches (my absolute favorite - nutritious and quiet!), discoid roaches, black soldier fly larvae (nutrigrubs).
- Occasional Treats: Mealworms (sparingly - fatty), waxworms (rare treat - very fatty), earthworms/nightcrawlers (many love these!).
- Size Matters: Prey should be no wider than the space between the skink's eyes. For adults, that usually means medium crickets, 1/2" dubias, etc.
- Supplementation is CRITICAL: Dust insects lightly with calcium powder (WITHOUT D3) at almost every feeding. Dust with a quality reptile multivitamin (containing D3 & A) once or twice a week. Gut-loading your feeder insects with nutritious veggies (carrots, sweet potato, greens) 24-48 hours before feeding is vital too!
- Feeding Frequency: Adults: Every 2-3 days. Offer as many appropriately sized prey items as they'll eat in about 15-20 minutes. Juveniles: Daily or every other day. Observe body condition - don't let them get fat! They store fat easily.
One quirk? They are SHY eaters. Don't watch them like a hawk. Drop the food near their hide and walk away. They might not eat every time, especially if stressed (like after a move). Mine sometimes ignores food for a day or two, then eats ravenously the next. As long as weight is stable, don't panic.
Behavior & Handling: Setting Realistic Expectations
This is crucial for deciding if a red eyed alligator skink is right for you. Let me be brutally honest:
- They are NOT handleable pets. Full stop. They stress incredibly easily. Handling should be reserved for absolutely essential tank maintenance or health checks. Even then, be quick and gentle. That cool defense mechanism? They can drop their tail (autotomy). While it's not as common as in some geckos, it can happen if they feel severely threatened. Seeing a dropped tail is heartbreaking and stressful for both you and the skink. Just... don't handle them unnecessarily. Enjoy observing.
- They are Masters of Hide and Seek. You might go days without seeing them, especially when new. They burrow, tuck themselves into tight spaces, and become invisible. This is normal behavior. Resist the urge to dig them up. With time and a secure environment, they often become bolder and might sit partially visible more often.
- Vocalizations: Yes, they can squeak! It's a high-pitched, surprising sound. Usually indicates distress (like being startled during cleaning) or sometimes during interactions between males and females (though they should generally be housed alone).
- Activity: Primarily crepuscular and nocturnal. You'll see the most movement early morning or evening. They sometimes sit partially submerged in their water dish – adorable!
Health & Common Issues: What to Watch For
Generally hardy *if* set up correctly. But watch out for:
Issue/Symptom | Possible Cause | Action Needed |
---|---|---|
Lethargy, loss of appetite, sunken eyes | Dehydration, low humidity, internal parasites | Check humidity immediately (should be 70-90%). Ensure water dish is clean/fresh. Vet visit if persists. |
Labored breathing, mucus around nose/mouth | Respiratory Infection (often from cold temps + high humidity without enough ventilation) | URGENT VET VISIT! Requires antibiotics. Check temps/humidity balance. |
Stuck shed, especially on toes/tail tip | Chronic low humidity | Increase misting frequency, ensure deep moist substrate, check humidity gauge accuracy. Soak carefully in shallow lukewarm water if skin is constricting. Prevent with proper humidity. | Bloating, lack of bowel movements | Impaction (often from ingesting substrate or large prey) | Warm soak, gentle belly massage. Ensure prey size appropriate. Vet if no improvement. Use feeding dish to minimize substrate ingestion. |
Sudden tail loss | Extreme stress or mishandling | Minimize disturbance, ensure plenty of hides. Tail usually regenerates, but often stubby and darker. Prevent by avoiding handling. |
Annual checkups with a reptile-savvy vet are recommended, even if your **red eyed crocodile skink** seems fine. Fecal parasite checks are a good idea, especially for wild-caught individuals (though captive-bred is always preferred).
Finding Your Red Eyed Alligator Skink: Purchasing & Ethics
This is important. ALWAYS prioritize captive-bred (CB) individuals. Wild-caught (WC) skinks are often heavily stressed, loaded with parasites, and their collection impacts wild populations. Captive-bred are generally healthier, more adaptable, and less stressed.
- Reputable Breeders: Your best bet. Look for breeders specializing in geckos or unusual lizards. Check reviews, ask about their setup and breeding practices. Expect to be on a waiting list. Prices: $200 - $400+ USD for CB juveniles, depending on lineage and breeder reputation.
- Reptile Expos: Can be good, but BE CAREFUL. Ask specific questions: Is it CB? How long have they had it? Watch the animal's condition – alert? Clear eyes? Good weight? Avoid vendors selling tons of different cheap animals or who can't answer basic care questions. Don't impulse buy!
- Specialized Reptile Stores: Sometimes have them. Again, ask about source (CB vs WC) and observe the animal's health and enclosure conditions in the store.
- Online Classifieds (MorphMarket, FaunaClassifieds): Connect directly with breeders/sellers. Vet them thoroughly. Ask for recent pictures/videos. Insist on overnight shipping with proper packaging and live arrival guarantees. Never ship during extreme temperatures.
Price Warning: If a price seems "too good to be true" (significantly under $150 for a juvenile), it almost certainly is. It's likely wild-caught, sick, or misrepresented. Paying more for a healthy, ethically sourced CB animal from a good breeder saves you heartache and vet bills later.

Frequently Asked Questions (FAQs): Your Doubts Cleared
Are red eyed alligator skinks good pets for beginners?
Hmm, tricky. Their care *needs* (high humidity, specific temps, no handling) are more demanding than a leopard gecko or corn snake. If a beginner is meticulous, does TONS of research beforehand, and understands this isn't a cuddly pet, it's *possible*. But honestly, having experience with maintaining stable humidity in a bioactive setup or similar is a big plus. Their sensitivity makes them slightly less forgiving than true beginner reptiles. I'd recommend gaining some reptile experience first unless you're incredibly dedicated and patient.
Do red eyed crocodile skinks bite?
They *can*, but it's incredibly rare. They're more likely to freeze, flee, or play dead than bite. Their jaws are small and not designed for serious biting. A bite would likely feel more like a pinch than anything damaging. The bigger risk is them injuring themselves trying to escape if mishandled. Just... don't handle them, and biting becomes a non-issue.
Can red eyed alligator skinks live together?
Generally, no, especially males. They are solitary in the wild and territorial. Housing two together, even females, often leads to stress, competition for resources (hides, food), and potentially injury. Breeding pairs are sometimes cohabitated briefly under expert supervision, but separation is usually needed after. For pet owners, one per enclosure is the only responsible recommendation.
How often does a red eyed alligator skink shed?
Juveniles shed more frequently as they grow, maybe every few weeks. Adults shed less often, perhaps every 1-2 months. You might not even see it happen because they often eat their shed skin! Ensure that high humidity is maintained to allow for clean, complete sheds. Stuck shed, especially on delicate toes or tail tips, is a sign humidity is too low.
Do red eyed crocodile skinks need UVB light?
It's not as critically essential as for diurnal basking lizards like bearded dragons. However, providing low-level UVB (like a 5.0 UVB linear bulb or Arcadia ShadeDweller) is increasingly considered beneficial for their overall health, calcium metabolism, and well-being, even for nocturnal/crepuscular species. If you provide UVB, ensure there are plenty of shaded areas and hides. If you choose not to use UVB, strict attention to supplementing their diet with Calcium (with D3) and a multivitamin is absolutely mandatory. Personally, I use UVB because the potential benefits outweigh the minimal cost and effort.
Why is my red eyed alligator skink always hiding?
This is completely normal behavior! They are prey animals in the wild. Hiding is their primary defense. If you just got them, they need weeks or even months to settle in. Even established skinks will spend most of their time tucked away, especially during daylight hours. Ensure they have ample, secure hides. As long as they are eating well when food is offered and appear healthy (good body weight, clear eyes, clean vent), constant hiding is just them being a typical, shy red eyed alligator skink. Resist the urge to disturb them constantly to check. Enjoy the glimpses you get!
My red eyed crocodile skink isn't eating! What's wrong?
First, don't panic immediately. They can be finicky eaters, especially when new or stressed. Ask yourself:
- Is the environment correct? (Temps/Humidity spot-on? Check your gauges!)
- Are you offering appropriate prey? (Size? Type? Tried earthworms?)
- Is the tank too open? (Add MORE hides and clutter!)
- Are you watching them? (Try leaving food near their hide overnight.)
- Is it breeding season? (Appetite can fluctuate.)
The Bottom Line: Is the Red Eyed Alligator Skink Right For You?
Owning a red eyed crocodile skink is a unique experience. It's not about interaction; it's about creating a miniature, thriving slice of rainforest and witnessing a fascinating, ancient-looking creature go about its secretive life. They reward patience and observation.
Choose one if:
- You love unique, prehistoric-looking reptiles.
- You prioritize creating a beautiful, naturalistic terrarium.
- You enjoy observing natural behaviors over handling.
- You are meticulous about maintaining stable humidity and temperature.
- You understand and accept they are shy and will hide often.
- You can commit to their potential 10-15 year lifespan.
- You can afford a captive-bred animal from a reputable source.
Think twice if:
- You want a lizard to handle frequently.
- You need a "display" animal that's always visible.
- Maintaining high, stable humidity sounds like a chore.
- You prefer low-maintenance pets.
- You're on a tight budget (setup + animal costs).
Seeing my own red eyed alligator skink peeking out from its cork bark after months of near invisibility, or watching it gently swim in its dish under the moonlight, makes all the setup effort worthwhile. They're a captivating window into a different world, right there in your living room. Just know what you're signing up for, get the setup perfect from day one, and you'll have an amazing little dinosaur companion for many years. Good luck!
