Besides her being hungry I would put a towel around her tub so she can't see anything. Do that for a week, maybe without seeing any movement she'll settle down. Of course, feed her normally, but keep that towel up so she can't see you walking around in the room.

When I bought my black pastel, he was the same way. Of course, I put him by himself to quarantine, but every time I went in there he would strike. I completely covered his enclosure so he couldn't see anything. He's settled down a lot now. Of course, he was just a wee one. But, it can't hurt right?
