She's in ... just goes to show how much smarter the females (or maybe just more food oriented?) are.
The female has been in there twice for a snack. It still takes her awhile to find the entrance and she gets a little freaked out when she wants out and can't find the hole but I'm sure she'll get better at it.
Terrible picture but proof she's using it (I added some chaeto for now to make it less scary):
