I recently noticed my Coral Beauty has some "white salt spots" on one of it's sides. All of my other fish are fine with no spots.....2 percs...1 bg chromis...1 yellow goby. The Beauty has shown no signs of rubbing against rocks or swimming in a strong current and still has a voracious appetite. I have been feeding with some fresh garlic soaked food this past week. Should I wait to see what happens or treat right away?
