Naso's are iffy tangs to keep. They like lots of surge so if you do not have it place a powerhead near the surface of the water.

They eat brown algae so make sure some brown algae is part of there diet.

I suggest as a preventative measure you do the garlic extreme feeding regime as you know that there is ich in your tank.
