I have two clownfish I bought 6 days ago from a LFS. I put them in a QT where I have been monitoring them diligently. They were doing ok and the one had cloudy eyes since I brought him home. I had to do a large water change on Tuesday which maybe stressed them out. Now, they are both breathing heavy and on the bottom of the tank and losing some color. They stopped eating as of yesterday. I started treatment for everything since I cannot figure out what it is. They don’t have spots nor are they “sloughing slime”. I have attached a video of me attempting to feed them some frozen food and them laying there ignoring it to breath. So pardon the food particles…any suggestions?
