Alternanthera rosaefolia? pics

I was sold this plant as "some type of hygro" the other day but after looking at pictures I'm not so sure. It looks more like Alternanthera rosaefolia to me right now, but I could be wrong. At any rate I would also like to know if it will need anything special from me to live, it's a beautiful plant. I have a feeling that it will need high light, I have 2wpg now but I have positioned it right underneath the light so it gets the most benefit from it.

Edit: I just found a site that called Alternanthera rosaefolia "red hygro." How can it be called hygro when it's not hygrophila? I guess that's what it is though anyway.
