黑尾大勾旗

Moenkhausia costae — Black-Lined Tetra

The Black-Lined Tetra (Moenkhausia costae) is a robust, silver-bodied tetra with a prominent black horizontal stripe running to a black-tipped tail, reminiscent of a large hook — giving rise to its "大勾旗" trade name. It is an active, hardy schooling fish from northeastern Brazil that adapts well to a range of water conditions. A great choice for community aquaria needing an eye-catching mid-water swimmer.
