So I bought a heniochus about a month ago off line. He arrived super healthy then a couple white spots looking like sand started to appear. I moved him to my 50 gal quarantine tank and slowly started dropping the salinity from .25 down to now currently .08 (using a refractorometer). It has been at .08 2 weeks going on three starting tomorrow. The banner fish itself has an extremely healthy appetite and even gets fussy if I do not feed it at least 3 times a day. The problem is the 2 original spots just keep getting bigger and bigger. They do not seem to bother the fish and it doesn't scratch or rub against anything but I am a bit worried that the spots are not disappearing. Anyone have any thoughts or advice?
Thanks
