Well here's the issue. I had/have ich in my 250 gallon SW tank. I started hyposalinity and got the SG down to 1.009 about 3.5 weeks ago. It has drifted between 1.009 and 1.011 during this time span. Just checked it and it is 1.010. Now my hippo tang who started the whole ich problem when I introduced him to the tank about 5 weeks ago has developed 4 to 5 large raised white bumps. All other fish seem to have recovered from the ich. These white bumps look different than the ich I had previously. He seems to be behaving normally. No scratching, eating normally, not hiding. What could this be that has developed while at the lower salinity?
