Can Red-footed Tortoises eat Peace Lily?

Why

[confidence: high] [source: The Tortoise Table plant database, ASPCA Toxic Plant List cross-referenced with exotic reptile veterinary guidelines, peer-reviewed herpetology or veterinary toxicology literature.] Peace Lily (Spathiphyllum spp.) contains insoluble calcium oxalate crystals that cause intense oral irritation, drooling, swelling of the mouth and throat, and gastrointestinal distress in tortoises. Red-footed Tortoises are not known to have any tolerance for calcium oxalate crystal-bearing plants, and ingestion should be considered hazardous.
