Caring for your Gyldenstolpe's worm skink
Isopachys gyldenstolpei
Basic Information:
Gyldenstolpe’s Worm Skink is a small, fossorial lizard species native to Southeast Asia, particularly in regions of Thailand. This species has a smooth, elongated body with reduced limbs, giving it a worm- or snake-like appearance. Adults typically reach around 4–6 inches in length.
They are highly secretive and spend nearly all of their time burrowed beneath the substrate. Due to their fossorial nature, they are rarely seen above ground and are best suited as display animals within naturalistic or bioactive setups. Their behavior is subtle, making them ideal for keepers who enjoy observing hidden ecosystem activity.
Lifespan:
Estimated 5–10 years in captivity with proper care.
Sexing:
Sexing is difficult and not commonly performed.
• Males and females appear very similar
• Differences are subtle and typically require expert examination
Enclosure:
• Minimum: 5–10 gallon enclosure
• Recommended: 10-gallon or larger for stability
Provide a secure enclosure with deep substrate. Since they spend most of their time underground, enclosure design should focus on below-surface habitat rather than visual display.
Substrate:
A deep, moisture-retaining substrate is essential, such as:
• Organic topsoil
• Coconut fiber
• Bioactive substrate mixes
Substrate should be several inches deep to support constant burrowing.
Lighting & Temperature:
• Basking Spot: Not required
• Ambient Temperature: 75–82°F
• Cool Side: 72–75°F
• UVB Lighting: Not required. Provide a natural day/night cycle
Stable, moderate temperatures are ideal.
Humidity:
Maintain moderate to high humidity (60–80%).
Substrate should remain slightly moist but not waterlogged.
Food:
Gyldenstolpe’s Worm Skinks are insectivorous.
• Feed small invertebrates such as small worms, larvae, and tiny insects
• They may rely heavily on microfauna in bioactive setups
Due to their secretive nature, feeding may not always be observed.
Water:
They obtain most of their moisture from the substrate. Light misting helps maintain hydration.
Gyldenstolpe’s Worm Skinks are a unique choice for keepers interested in fossorial reptiles and bioactive systems. Their hidden lifestyle and unusual appearance make them a fascinating addition to specialized enclosures.
