clear film in water

ah cheers guys! I was wondering what the slime was with my pac too, noticed it every time he takes a bath. I've had a read through the thread, I have noticed him puff up but he does that when he's digging or if i'm prodding him gently and it's never anything major like he's stressed or anything, so I'm glad it's skin and nothing serious!
