I recently got a ruby longfin fairy wrasse from liveaquaria (1 week ago). For the past 3 days hes been upside down on the bottom of the tank, sitting still. He still tries to eat whenever i put in pe calanus or mysis shrimp. He looks healthy, not skinny, or dull colors or marking on his body. I acclimated him slowly to the tank, temp first then slowly mixed their water. Water pararmeters are, 1.025 salinity, 0.3ppm po4, alk of 11.0 and No3 of 10ppm. Any help would be appreciated
