Powder Brown Tang Sick!!?

[fishyfolks]

Hi everyone,

I am pretty new to this forum - We have only had my tank up and running for just over 1 year. We added a BEAUTIFUL Powder Brown to our 90 gallon about 3 weeks ago. Yesterday he (or she) looked awesome. Tonight when I went to look at him he is totally COVERED in little white spots that kind of look like bubbles?? They are on his fins and even on his 'eye lids'. We have about 10 other fish and none of them have a spot to be seen? Our salinity is .025, ph 8.2, ammonia 0, nitrate and nitrate 0 ish. Does anyone know what it could be? We do very regular water changes (2 a month) and we have neve seen a fish get this sick looking overnight???? i am pretty sure that after looking at pics of ich on the net - that isn't the problem here. Please if anyone has any ideas please let us know. Thanks sooooo much
