Oh wow, he looks grotesquely disfigured. Stop feeding him for awhile! Add a touch of salt. What else is in the tank? Can you not feed the tank at all or are there other fish that need food? What kind of pleco is it anyway?
I agree that a pleco will not eat anything 'by accident.' I watch all of mine eat from time to time and they never just swallow, they are very picky and they scrape the food.
