Purple Tang has Ick or Velvet?

[Lionsreef]

My purple tang which I've had since December is completely covered with white spots today. It ate normally normally tonight and no other fish in the tank have any similar spots. I did add a bellus angel to the DT about 9 days ago that i received from a reputable store that quarantines for >30 days. Before i placed the Bellus in my DT I had it in an observation tank for 14 days.

Any idea what this is and what i should do next?

This is the quarantine process from the stores website: "Upon arrival in our facility all newly acquired Marinelife undergo a full quarantine.This involves a series of dips and manual removal of any pests, followed by an observational period, and additional chemotherapeutic treatments if necessary. Routine observations ensure that our corals remain pest free. All fish undergo treatments for various diseases, parasites, and bacterial infections as part our standard quarantine period."

Should i catch and move all my fish to quarantine for treatment on just the purple tang showing signs?
