Upside Down Catfish won't eat - its been over a week

[FrozenFins]

I got these upside down catfish from my lfs a little more then a week ago. They havent eaten once. The guy at the LFS said they will anything. But mine wont even come out for feeding, I have tried feeding them at night, and they still wont even take a nibble. I have tried frozen blood worms both at night and during the day, but they dont even awknowlodge that there is any food in  the tank. 

Any tips to get these guys to eat?

I don't have any direct experience but here's a thought. Try taping some opaque paper on the outsides of the tank to block out anything that may be making them nervous like a tv flashing, people or pets moving around, lights coming off and on unexpectedly or whatever. My corys dive for cover whenever I forget to turn the hall light off and walk into the room casting a shadow.

Have you treated them for internal parasites at all? I can't remember from your first post.

No, because they have round and very fat bellies. So they must be eating something, I just dunno what they have been eating.
