Seachem GarlicGuard is an all natural garlic scented odour and flavour enhancer for freshwater and saltwater fish. Research has shown that many fish are attracted to natural odours, such as garlic. Simply mix GarlicGuard with any food item, such as Seachem’s NutriDiet Flakes, to attract the interest of finicky eaters, e.g. discus and marine angelfish.
