Blue Chromis (Chromis cyanea) sick but no physical evidence to know how to treat

[ahubele1]

For the past 3 days, my Chromis has shown signs of lethargy, has been swimming backwards/sideways, and has labored breathing. There is no physical evidence for me to diagnose it (no white/red spots on fins or body, nothing bulging on it, etc.) I've also tested my water and the levels are perfect as of now. Please help me figure out what is wrong with the poor thing and let me know what I can do to treat it.
