Hello my R2R friends. I have a Blue Hippo Tang who started rubbing against the rocks about 2 days ago. She doesn’t have any spots on her, and her color isn’t fading. From what I’ve read so far, it seems like she may be in the beginning stages of ich or velvet. Do I need to place her in QT, along with my 5 other fish? What type of treatment will they need? Also, if I have to place my lawn mower blenny and diamond goby in QT, what should I feed them? They normally have plenty to eat in the DT. This will be my first “go round” with treating potentially sick fish. Is there a treatment that can be done in my DT? I have lots of coral and CUC in the DT as well. Any advice will be greatly appreciated.
