Product Details

Anostomus Ternetzi is a distinctive freshwater fish from South America, admired for its elongated body, bold patterning, and classic headstander swimming behavior. This species brings a unique look and active personality to larger freshwater aquariums.

Because Anostomus species can become territorial as they mature, they are best kept in spacious aquariums with plenty of swimming room, hiding areas, and compatible tank mates. They are especially appealing to hobbyists who enjoy unusual and less commonly available aquarium fish.
