I got this coral beauty from biota on the 6th. I did not quarantine it, looking back probably a mistake. I noticed a small white spot near its gills shortly after adding it and thought maybe it had caught itself on a rock. But today it looks like this. Fish seems to be eating well, swimming. Sorry for the cloudy water I hard to move a lot of rocks to catch the lil guy. Any ideas what this is and how to treat?
