Need some advice on quarantining a pintail fairy wrasse. I just got him today. He’s in my QT with my royal gramma who I‘ve had for a week. The QT is a 20g bare bottom with 2 3” PVC pipes. I‘m not treating the the tank yet. I usually give my fish a week to acclimate. My last experience with a wrasse was a Lubbock Fairy Wrasse and it was not good. He died 5 days after getting him. I was told this wrasse does not need sand. Is there anything I need to do or add to the tank to decrease his stress? In my experience wrasse seem like very sensitive fish. I’ve heard they are sensitive to their reflection.
