From 2000 – 2008 there was very little online discussion about the use of garlic as a natural remedy for treating tropical fish. There were a few sporadic references to , which is marketed as an Appetite and Flavor Enhancer for both freshwater and marine fish. For the first time, the Seachem product referenced garlic oil, rather than smashed up cloves, minced, or powdered garlic. This was the first I read about treating fish with garlic that had an air of legitimacy. Oils are more stable and predictable and calculating dosing would be a lot more accurate when dealing with an oil. Even so, the product was not advertised as a medicine, but rather a supplement. The popular online fish store, elaborated that Garlic Guard contains the active ingredient allicin, which contains powerful antioxidant properties that can lessen free radical damage to cells. Of course they were careful to say that it can lessen free radicals, not that it does. Very few supplements are thoroughly tested in humans, I have to doubt that much is done with aquarium fish. Regarding its affects treating parasites, Seachem specifically states in their directions for Garlic Guard that it should be used with other Seachem products: “For enhanced effectiveness against Ich and other parasites use Seachem’s Focus and Metronidazole as follows: Add 1 measure of Metronidazole to 1 measure of Focus per tablespoon of frozen food. Completely soak this food mix in Garlic Guard, refrigerate, and feed once or twice daily for 1-2 weeks.”

In terrestrial veterinary practice "preventive medicine" is often erroneously considered synonymous with vaccination and "deworming" schedules. Of course, preventive medicine encompasses much more, including provision of proper nutrition, maintenance of a healthy environment, and management of other disease risk factors. For pet tropical fish, the lack of available vaccines and well worked out chemical prophylaxis regimens greatly increases the importance of the "other" areas of preventive medicine. Preventive medicine should begin before the pet fish owner sets up their tank or pond, and includes many areas considered "Husbandry".
