The Head & Tail Light Tetra (Hemigrammus ocellifer) is a peaceful, schooling fish native to South America, known for its silvery body and distinctive light-reflecting spots near its head and tail. These spots, which are pinkish or orange, give the fish its common name and can be more vibrant in darker gravel and backgrounds. They are relatively easy to care for and thrive in planted community aquariums, making them a popular choice for beginners.
