Can Greek Tortoises eat Peace Lily?
Spathiphyllum wallisii
Safety verdict
Toxic
Why
[confidence: high] [source: The Tortoise Table plant database (tortoisetable.org.uk), exotic reptile vet review, and ASPCA Toxic Plant List cross-referenced with chelonian dietary guidelines] Peace Lily (Spathiphyllum spp.) contains insoluble calcium oxalate crystals that cause intense oral irritation, swelling, and gastrointestinal distress in tortoises. Greek Tortoises (Testudo graeca) are particularly vulnerable as herbivores with no physiological tolerance for oxalate-laden plant materials at this concentration.
How much / how often
None — should not be offered at any quantity
Preparation
No preparation method neutralizes the insoluble calcium oxalate crystals; the plant should be kept entirely out of the tortoise's enclosure and foraging area.
