I have a 120G with 7 fish SFE and various crabs/snails/shrimps. I just noticed both my blue hippo tang and flame angel have are just starting to get develope ich. What would be the best idea to go about treating this? Should I try to catch the affected fish and freshwater dip them and just feed everything dipped in garlic + selcon for a few a while Or should I try to QT and hyposalinity. I do not have a QT tank settup, so I can go buy a 55gallon at the store but it wont be cycled. I also have some my liverock in a settup that took a VERY LONG time to get settup, so I woul d like to avoid taking it down, If i need to catch fish is there any sort of trap I can make?
