Hi Jack ,
Carlos is right.
It is a pothos. It looks as though this cutting has been re-potted in coco fiber
They are forgiving plants, in that they grow quickly, and root easily.
I don't think the pothos would be 'killed' by you pac of it accidentally digs by it or even digs it up.
But you don't want your pac to eat the leaves, accidentally.
I don't have pacs.
Maybe post a separate question in the pac area of FF or do a search for safe pac plants.
This plant is very commonly used in enclosures, especially tree frogs. However, there is no real risk of a tree frog biting the leaf. Tree frogs enjoy sleeping on top or on the underside of the leaves.
Philodendron are a very large group of plants in the Araceae family- most of which are toxic
if the leaves are ingested ( mostly we worry about cats and dogs).
I believe people do use them in their pac enclosures. But there is that chance you could miss a leaf that fell off or or accidental ingestion!
So, I will agree with Carlos...might be best to leave it out ? I'm a scaredy-cat.
