About this species

A small, alert lizard often found basking on sunlit rocks or among tussock grasses. It is one of the few species of lizard present in New Zealand.

Enrichment & behavioral stimulation

Grass Skink is ground-dwelling — enrichment centers on basking variety, digging, and foraging puzzles.

  • Use stacked rocks and branches to create varied basking heights and a broad thermal gradient.
  • Add sturdy low climbing structure appropriate to the species.
  • Scatter insects and offer greens in different spots and times to extend feeding activity.
  • Use rock bowls or wobble feeders to slow eager feeders and add problem-solving.
  • Provide a dig area of safe substrate to satisfy burrowing instincts.
  • Offer varied UV and heat zones so the lizard can self-regulate exposure.

Housing & Social Behavior

Variable

Can be kept in pairs, but ensure no bullying occurs between individuals.

Housing guidance is general and based on species-typical behavior; always verify against current husbandry references and observe individual temperament.
