My biggest problem with the use of garlic is the mythology that has developed regarding it. This all began quite simply and innocently. Kelly Jedlicki was studying the use of garlic as an intestinal dewormer. For those who don't know who Kelly is, she is affectionately referred to as the "Puffer Queen" as they are her favorite fishes and oftentimes are brought into the trade polluted with various worms. As I said, she was examining the effectiveness of garlic against nematodes and cestodes on impacted puffers when she noticed a general decrease in Cryptocaryon irritans incidence. Later on, she proposed feeding garlic to fish as a preventative for Cryptocaryon irritans. From there the legend of garlic has spread. Feeding garlic to fish is now an accepted cure for Marine Ich by some individuals. Furthermore, I have read of people merely hanging cloves of garlic in their tank in an effort to ward off the parasites, like some sort of bad vampire movie. And lastly, I have recently heard of a surprising number of hobbyists who soak their corals' food in garlic in an effort to combat possible pathogens when target feeding them. It goes to show that garlic has become an all-purpose wonder drug in some peoples' eyes based on little more than anecdotal observations.
