Help cory acting strange

[crazywolf]

I have a cory acting very sick. He's kind of floppy around when he moves almost like his back is broken or something odd like that. He doesn't swim and he's breathing rapidly. I have 6 in his tank and the others are fine and acting normally. He is a darker color than the others not sure if this matters. I checked my parameters and everything seems fine. he's just laying there on his side. It's just so sad. Please help
