Brown spots on new Longnose Butterfly? Help! **PICS**

Does anyone have any idea what these spots could be? The fish is still in my QT tank at the moment and is eating like crazy. There is no wierd behavior but I did notice these brown spots.

Thanks!

I would double check water quality first: pH, alkalinity, ammonia, nitrite, nitrate, salinity, temperature, etc.
