Mine is a 120g mixed reef tank. Mostly soft coral as I’m still figuring things out with the hobby. I think going fallow for 80 days and QT observation/treatment is my best option to ensure that all parasites are killed off and fish are disease free upon placement back to my DT. I know all the surviving fish were exposed to what killed the other fish so I think treatment is a definite. Maybe a formalin bath or dip prior to placement into sterile QT. Prazi and/or some other antibiotics. Opinions?
BTW, thanks 110reef for your input. Much appreciated.
