Red-Eyed Crocodile Skinks are striking reptiles known for their armoured, crocodile-like scales and bright orange-red eye rings. Their prehistoric appearance has made them increasingly popular among reptile keepers.

Housing & Enclosure Requirements

Red-Eyed Crocodile Skinks require a humid, naturalistic enclosure that replicates a tropical forest floor.

Typical enclosure size:
45 × 45 × 45 cm (18 × 18 × 18 inches)

Key enclosure elements:

  • Moderate temperatures: around 24–28°C

  • High humidity with regular misting

  • Deep substrate such as coco fibre or soil blends

  • Hides, bark and plants for cover

  • Shallow water area

A well-planted enclosure helps create a secure environment and encourages natural behaviour.

Diet & Nutrition

Red-Eyed Crocodile Skinks are insectivores, feeding mainly on live insects.

Common feeder insects include:

  • Crickets

  • Small roaches

  • Mealworms

  • Waxworms (occasionally)

Adults are typically fed every 2–3 days, with calcium and vitamin supplementation used regularly to support good health.

Temperament & Handling

Red-Eyed Crocodile Skinks are generally shy and secretive reptiles. They prefer to hide among plants, bark and substrate rather than interact with people.

Handling should be kept to a minimum, as it can cause stress. Instead, they are best appreciated by observing their natural behaviours within a well-designed enclosure. Their unique appearance and interesting behaviours make them a popular display reptile.

 

Is a Red-Eyed Crocodile Skink Right for You?

Red-Eyed Crocodile Skinks can make fascinating pets but require a carefully maintained environment.

Prospective keepers should be prepared to:

  • Maintain warm temperatures and high humidity

  • Provide a planted, naturalistic enclosure

  • Feed live insects regularly

  • Limit handling to reduce stress

For reptile keepers interested in tropical species, Red-Eyed Crocodile Skinks are unusual and rewarding reptiles to observe.
