I had this Yellow Wrasse for almost 2 months now in DT and it's agile and eats well. Today I saw white patches under moon lights on both sides of the fish and it's fins but completely not visible when I turn to white lights. I have taken pics using both these lights. Is the wrasse infected with something like parasites or flukes? Should I move it to QT? I normally use JBL punktol for ich, can this be used? Heard copper is not good for them. Please suggest
