I currently have 4 female Randall's Anthias in QT treating with metro for white stringy poop. Am planning run copper and prozipro later the course of QT. I am thinking getting more Anthias in groups before the copper treatment so I can QT them at the sametime. What would be good different Anthias for my current Randalls? And should the new Anthias be all female? I am looking at Dispar or Resplendent Anthias. Am leaning more to Dispar since I couldn't tell the difference between Resplendent and Randall's.
