Can Painted Turtles eat Chinese Evergreen?

Why

[confidence: high] [source: Exotic reptile and chelonian veterinary toxicology references (e.g., Mader's Reptile and Amphibian Medicine and Surgery), ASPCA Animal Poison Control plant toxicity database cross-referenced with chelonian dietary studies.] Chinese Evergreen (Aglaonema spp.) contains insoluble calcium oxalate crystals, which cause intense oral irritation, swelling, and gastrointestinal distress if ingested; these effects apply to aquatic omnivores like Painted Turtles that may nibble on plant material introduced to their environment. There is no safe dose, as even small ingestions can trigger significant mucosal damage.
