Aquarium Myths and Misinformation

The Dietary Supplements thing is a minefield, I'll say that. I agree with the other post about how good diet can be a tool to promote health/ward off trouble.

But what I wonder is in particular the issue of natural fish diet vs captive. For example, I have a Foxface Rabbitfish that for a long time refused to take any algae. It does now. It is supposedly omnivorous with some preference for algae. I've not found much written about what happens to fish when not fed their natural diet. The Foxface now eats algae and frozen so it's getting what I think is close to its natural diet.

I was surprised not to find Melafix and Pimafix addressed in the article. Maybe I just missed it.

I'd rewrite Dietary supplements as a “medication”:
Of course diet and supplements don't "medicate." I agree with the bolded section title, but the discussion under it, I think, could be modified. Supplements can improve immunity and health to resist infections. Supplements given to a sick fish can improve the fish's immune system. A healthy diet with supplements can maintain a fish's resistance to bacterial and viral infection (or just prevent their display), but can't always prevent a parasitic attack. A good example is an aquarium known to contain Mycobacterium marinum, but the fish s how no signs of being infected. Diet and supplement in regard to parasites: I have seen (eDNA) the parasite Uronema marinum (Uronema) in aquariums in which the fish show no signs of infection. I attribute this to pristine water, proper tank flow, low to no fish stressors, tank cleanliness, and a good immune system provided by proper foods and supplements.

I'd say this is an excellent article with perhaps the noted concerns.

I will always want to read articles by such knowledgeable people.
