First Mortiis Pics

Here's a few pics of Mortiis, on his (or her) first day in his (or her?) new tank :

Apologies on the quality and the water on some of them, as its pretty humid in the tank.

Any help with possible sex would be appreciated, I can't get a good enough look at the pectines or anything on the underside for that matter! I don't want to go poking around to have a look when its just settling in.
