Hey everyone so I’ve got a 55 G reef that previously had ich and after I left it 3 months empty I added 2 clowns a damsel, a lavender tang , a watchmen goby and a lawnmower Blenny. The only fish that flashes on occasion is the lavender tang but he’s eats like a pic and hasn’t shown symptoms in weeks. To transfer my fish to my new 100g system should I quarantine the fish separately with copper or saltwater dip them? If one fish flashes I could assume the rest of the 55g tank fish have ich too but just don’t show it. Any suggestions? Thanks
