Overview
\nThe American Flagfish is a striking and unique freshwater fish named for its resemblance to the U.S. flag, with its iridescent scales and red, blue, and white markings. It is a member of the killifish family and is known for its algae-eating habits, making it a great addition to planted aquariums.
\nOrigin
\nNative to slow-moving waters, marshes, and ponds of Florida, USA, the American Flagfish thrives in warm, vegetated habitats with plenty of plant cover.
\nFeeding
\nAmerican Flagfish are omnivores, with a strong preference for vegetation and algae. They readily consume:
\nAlgae (a great natural grazer for planted tanks)
\nHigh-quality flake or pellet food
\nBlanched vegetables like zucchini and spinach
\nLive or frozen foods like brine shrimp, daphnia, and bloodworms for protein
\nTank Mates
\nWhile generally peaceful, American Flagfish can be semi-aggressive, especially males during breeding. Suitable tank mates include:\u2028 Small peaceful fish like tetras, rasboras, and corydoras\u2028 Larger shrimp species and snails\u2028 Other killifish or small livebearers
\nAvoid:\u2028 Long-finned or slow-moving fish (e.g., bettas, fancy guppies) as they may nip at fins\u2028 Extremely small or timid species that may be outcompeted for food
\nAggression
\nMales can be territorial and aggressive towards one another, especially during spawning. It is best to keep either a single male with multiple females or a small group in a well-planted tank to diffuse aggression.
\nExperience Level
\nIntermediate \u2013 While hardy, they require a well-maintained, algae-rich tank and can be aggressive if not housed correctly.
