i have a recently bought a plant that i think is called a sweetheart plant, a species of philodendron and it has red sap. i keep anoles and tree frogs and was reliably told that toxic plant in a viv could eventually kill them through crickets eating the plant then the lizards and frogs eating the crickets. can anyone tell me first of all wether this is true, and if so is the philodendron a toxic plant.
