Catfish Everclean... again

We have been slightly concerned about Catfish, during the last few weeks as she/he has been fairly inactive and apparently when I was away in Disneyland, she/he didn't noticeably move. Not only this but she/he was failing her duties as a window cleaner (perhaps on strike in my absence).
However, after cleaning the tank and rearranging the decorations, she/he seems to be fine, moving about the tank...
but still not cleaning it as you may see from the photo. :D
