I just bought a small size foxface along with a blue tang 3 days ago from a lfs. Popped it straight into my QT. I saw it ate a few pellets the day I bought him. Today got back from work and saw it was sucked into a filter and not swimming away. I moved him away and let him be for a while and after that I saw it laying on the bottom. Decided to do a FW dip to see for flukes but nothing came out. No white spots either. Any idea what’s going on? Here is a photo of it during FW dip:
