The hyposalinity advice was great; I didn't know that option existed. How would corals (softies and LPS) react to that? I ask because my bf has had a persistent ich problem with his purple tang and a little bit on his naso, but it usually only lasts a day or two and is gone for a few weeks. He uses garlic and the fish behave normally. In regards to suggesting shrimp, I have noticed that skunk cleaners do a really good job of cleaning fish. Fire/blood shrimp have a tendency to be more reserved and hide more often from what I've seen and heard. My bf has both species and his skunks clean almost continuously; the blood shrimp rarely cleans, and he is an anomaly because he comes out often. Most blood shrimp hide the majority of the time, from what I understand.
