Golden Wonder Killifish

The Golden Wonder Killifish, Aplocheilus lineatus, is a striking freshwater fish known for its vibrant golden-yellow coloration and elongated, torpedo-shaped body. Growing up to 4 inches in length, this surface-dwelling species is an eye-catching addition to any aquarium. Its shimmering scales reflect light beautifully, creating a captivating display that draws attention from every angle.

The Golden Wonder Killifish is relatively easy to care for and can thrive in a well-maintained community tank, provided its tank mates are of similar size and temperament. It prefers a planted aquarium with plenty of floating vegetation to mimic its natural habitat.
