I recently bought 5 Lyertail Anthias from LFS. They all did fine for 2 weeks in the QT, but one of them developed this white patch about half the area of a dime on its right side near its belly. She is now back in the QT with API general cure, heater and air stone for aeration.
Can anyone identify what the white patch actually is and what the best course of treatment action is?
