It is not an anubia, IMO, but a closely related species. It looks to me, and I've seen this species out of a pot, so I know what the root systems looks like. I have several of these in pots at home.
Spathiphyllum wallisii (Peace Lily)
It is often used in paludariums and though classified as a non-aquatic, can actually survive for some time in an aquarium. Don't know why it's so expensive, because a plant like that is less than a dollar US.
The plant in the second picture looks really beat up. Ouch. Somebody's been munching on it.
