some of my anthias died and fish rubbing themselves on sandbed. Also have some dead fishskin I’ve been fishing out. So both clowns And powder brown tang have some kind of bubbles/white spots. Powder tang is not active, not eating nori. He was the most active fish. Clowns are acting normal though. And powder blue also scratching just got him yesterday though. I thought it was just extra bubbles from My return pump while it was running on almost empty. Also had high nitrates and phosphates so went to ocean and got a few handfuls of algae, cleaned it with coral dip. Stupid of me after reading later effects...sight
I’ve attached a video. Should I do copper or something without copper. 200 gal with sump Are they dying or sick? How bad is it? Please help. Thank you!
my fish: yellow, purple, brown, blue and dori tangs. Rabbit fish, clowns, damsels, flame and coral beauty, Watchman gobby, 6 line wrasse and mandalorian wrasse. Blue starfish and a bunch of snails, crabs.
