The American Flagfish is an attractive killifish with a coloration vaguely reminiscent of the American flag. In males, the body is light colored with an irridescent blue-green sheen. Numerous horizontal red, broken lines mark its flanks. A darker blotch marks the center of the body just below the dorsal fins. Females are tan and duller in color, with shorter fins and some dark mottling on the sides. Flagfish are peaceful fish that can be kept with most community species. However, they can be territorial with their own kind. They are best kept in pairs, or one male with a few females. Unlike many killifish, these fish are very hardy, and can be easily kept and bred in the home aquarium. Provide a heavily planted aquarium with subdued lighting. These fish will accept a variety of foods including small worms, crustaceans, insects, plant matter such as spinach or lettuce, as well as pellets and flakes. American flagfish are primarily freshwater fish, but they are known to enter brackish water, and can be kept successfully in brackish water tanks. They are sensitive to high temperatures, so keep them with temperate species that will tolerate slightly lower temperatures.
