What about your ph? what about salintiy? I posted a reply to this same question in the invert section, if you keep bouncing around and posting the same questions in different spots your gonna get alot of scattered answers. Posts regarding invert problems should be in the invert section. Posts regarding ich, which is what your initial post was about, should have gone in disease and treatment. It will be beneficial to you if you post in the coresponding categories, notice that we are in the fish only forum and the question is regarding an invert, and your ich question was in the invert section, granted it was regarding why your shrimp wasnt cleaning but the problem was ich not a disfunctional shrimp. Ich is like a weed, if you dont kill the source it will keep coming back and most likely the source is either bad water quality, stress, or an infected fish from your lfs. You should also keep questions pertaining to the same problem going in the same thread so people can get the "big picture". sorry if this is long but im trying to help you get some answers, which is why we all come here.
