This aroid needs a lot of humidity or it will slowly degrade. You can read up on it.

ASJ is correct. But in addition to humidity the species needs relatively low light due the species being a member of Anthurium section Cardiolonchium. Section Cardiolonchium includes Anthurium species with velutinous or velvet appearing leaf blades. Windy Aubrey in Hawaii has a large number of these plants with a large variation in the venation (vein structure) on the leaves. I'm told she grows them in both high humidity and fairly low light. The largest specimen I've personally seen has leaves close to 5 feet long and is housed in the collection at the Missouri Botanical Garden in St. Louis, MO. They also grow their large specimen in relatively low light.

Thanks everyone for your help, I will have to reconsider its position and conditions and I think I have just the place.
