Hello all, this is my first question on this thread.. I bought couple of fishes few weeks back such as butterfly, banner, foxface, fire clown and dottyback.. How from the few days I have noticed that butterfly and banner has white spot on their bodies which is I know is not a healthy indication at all. One of my friend suggested me to drop Water salinity until 1.017. So I have to remove all corals and other cleaning staff from aquarium. However they are feeding nicely as usual but their white still presist.
