So exactly 14 days ago I noticed white spots on both my clownfish and immediately QT my two clowns and YWG. I spotted the ich at about 1am and saw just one or two spots on my clowns when I woke up sometime early morning. They weren’t rubbing against rocks or sand and have been really healthy pre QT and currently during QT. So my question is if it was ICH wouldn’t it be visible for days and not just the short timeframe I saw it? My clowns did lay on the sand bed at night to sleep and now I’m wondering if I QT and am copper treating healthy fish. I have a thicker aragonite sand so idk how small particles could be stuck to their coat, but I just don’t understand how my fish look covered in Ich for the first time after owning them for a couple weeks only to have 90% of the spots clear up within hours. Any insight or suggestions would be much appreciated.
