In all seriousness, does this always show red? I had a fish some months back that exhibited some of this when he was placed in the tank. It was a yellowtail damsel, and the blue part of his body got all funny looking and streaky, but it wasn't red. He recovered a week later.
Sorry Kreblak, missed this question earlier. Yes, petecchial (to my knowledge) always shows up as red streaking, but it may not be as easily seen or may appear a different shade depending on a fish's color. But, don't confuse this with the normal stress and day/night color shifts that many fish perform regularly. Damsels are one of many fish that will shift their colors when scared or adjusting from light to dark conditions.
