Long story short -- we let the house cool off last night during the first cool evening of fall. Temp in the house had been regulating tank at room temperature. So the tank got down to about 70 degrees last night. It's typically 78-82. My clown fish died, my yellow tang will be dead in an hour -- and my sailfin is covered in what looks like velvet. All other water paramerters are "normal" slightly elevated nitrate and phosphate -- but not out of the ordinary. Other fish and organizms are fine. Did Temperature do in my fish?
