We just completed our second 30 day fallow for what we believed to be a ick or velvet outbreak. The first fallow was determined to be failure when we noticed small white dots on both our yellow tang and flasher wrasse. All fish were removed and treated with copper for 14 days and then transferred to a clean tank and appeared healthy with no further indications of illness. During the fallow we increased the water temperature, did multiple water changes and deep cleaned the sand bed, installed UV, and deep cleaned our sump. Once the tank completed the 30 day fallow we acclimatized two freshwater molly's to saltwater and introduced one into the display tank (the other was put in with the qt to ensure no illness remained). The molly was in the display tank for 5 days with no signs of illness so we decided to add back the yellow tang, flasher wrasse, salon wrasse, watchman goby, and mandarin goby. Today, day 6, one small dot has appeared above the molly's eye. The molly seems otherwise healthy with no flashing or unusual breathing.
So what do we do now? Is there anyway this is something more benign like a coral sting? The other molly in the qt is healthy with no dots, so we were considering moving it to the display tank as a confirmation test. The idea of a third fallow is overwhelming and we are not sure what we could have possibly done wrong (except maybe waiting longer after the mollies were introduced).
