    I have 9 neon tetras, one just hides behind the filter. He comes out of hiding to eat when I feed my fishes but goes back to hiding after. Is he sick? He's been doing this for days now.

    Are they new? Is it a new tank setup? Did you add any new additions?

    It is likely it is sick in my opinion.

    This is a common symptom with Neon tetra disease.

    However, sometimes dominant males stake out a territory away from the shoal and so it could be this.
