Nutrition is certainly important against most disease. The best examples are the internal bacterial and fungal diseases.

However, I also think that the role of proper nutrition should not be exaggerated. The inexperienced aquarists should not be duped into believing that good nutrition is the answer to all diseases A to Z.

I think ich and Odinium have little to do with nutrition. The relation of these disease with stress in general is also problematic, and even if prsent, should not be emphazised. This would hopefully promote their eradication by proper quarantine. These are pretty much diseases of physical confinement, unnatural concentration of patheogens.

Some external bacterial infections are also opportunistic. Some even very robust fish with great nutrition and little stress can get external bacterial infection without previous exposure and acquired immunity. De-emphasis with good nutrition is actually better, as it encourages the proper use of UV against external bacterial infection, especially during acclimation. These are also diseases of physical confinement, unnatural concetration of patheogens.
