I can't see anything sorry, try a good description umm... any symptoms of illness from the fish, are they moving lethargicly in any way? All I see in the photo are glass pebbles.

Sorry, I can't see anything either - glass pebbles and a normal looking bronze cory. Can you give us some more information? If the fish seems unwell, it might be better to post in the Emergencies section?
