I am currently QT'ing a fox face some chromis and 4 frags that I picked up this past weekend. Tonight I notice that the Foxface is starting to show signs of Ich. Can I treat the Ich with Kordon's Rid-Ich PLus witht eh frags in the QT tank. Frags are Zoas, Mushroom, Polyp, and some green stars. Can I treat the Ich or should I move the Frag to another location? Thanks!
