what is the brown buildup on my cleaner and coral banded shrimp? it is only on the shrimp and it is like they cant get it off.

Does it look like a burn mark? My scarlet cleaner had this once and it came off with a couple of sheds.

could be, what do you have in the tank that required Iodine other than the shrimp?
