The Head and Tail Light Tetra is a classic aquarium species that has been in the hobby for decades, beloved for the characteristic golden-orange iridescent spots that glow at the top of the eye and at the base of the caudal fin. These twin points of light give the fish its common names — Beacon Fish and Head and Tail Light Tetra — and are especially vivid under dim or blue-spectrum lighting. The body itself is a translucent silver with a faint lateral stripe, making the glowing spots even more conspicuous. Native to a wide range of South American river systems including the Amazon basin, this species is highly adaptable and tolerates a broad range of water parameters, which contributes to its enduring popularity among beginners. It is a mid-water schooling fish that is active throughout the day, constantly moving in loose formation with its schoolmates. Peaceful and non-aggressive, it is an excellent choice for community tanks housing other small tetras, livebearers, rasboras, corydoras, and peaceful cichlids. Its hardiness, attractive markings, and ease of care make it one of the most recommended beginner tetras available. Provide a planted tank with dark substrate to show the luminescent spots at their best.
