Head and Tail Light Tetra
Head and Tail Light Tetra(Hemigrammus ocellifer) is one of the oldest and most enduring aquarium tetras — kept since the 1930s and named for the vivid spots at the eye and caudal peduncle that resemble automobile headlights and taillights. The eye has a vivid red upper iris; the caudal spot reflects copper-gold. A classic aquarium fish with nearly a century of keeping history.
