Hemionitis arifolia (heart fern)

So I was browsing the local Wal-Mart for an interesting plant to put in a new hanging pot... and I found a really neat looking fern. Unfortuneately, the only thing printed on the plastic pot was" "FERN 4" " So... fern. Pretty vague... by chance I caught some forum post about a "heart fern", and after some searching it is in fact Hemionitis arifolia. Unfortuneately, all I can find are pictures of the plant, I can't find a lick of information about proper care of the poor thing. I'm hoping it kicks back, but it's been losing a few leaves every day now. Though, I'm pretty sure the leaves that are shriveling were already pretty sickly looking... It does have one nice new leaf (frond?) growing, and none of the major leaves are giving up. I'm crossing my fingers, as it's really pretty.
