When people say to add a piece of shrimp to a new tank, they mean to add a piece of fresh shrimp from the seafood department at the grocery store. The reason for this is to have it start to decompose in your tank. This starts the cycle. It introduces ammonia into your tank. Then, beneficial bacteria begins to colonize and turn the toxic ammonia into nitrite. Then, more bacteria colonizes to turn the nitrite into nitrate. Nitrate is removed through water changes and nutrient export. At this stage, I would not add a piece of shrimp. You have a fish in the tank. I would just monitor the ammonia, nitrite and nitrate levels.
