Lemon Tetra (Hyphessobrycon Pulchripinnis)

Lemon Tetra (Hyphessobrycon pulchripinnis) — A Warm, Golden Schooling Fish for the Planted Aquarium

The Lemon Tetra (Hyphessobrycon pulchripinnis) is a graceful and underappreciated schooling fish from the rivers of central Brazil. Named for its warm, translucent lemon-yellow body and vivid yellow-tipped dorsal and anal fins, the Lemon Tetra brings a soft, golden warmth to the planted aquarium that complements green aquascapes beautifully. Its subtle colouration rewards close observation — under good lighting, the body shimmers with a delicate golden iridescence that makes a school of Lemon Tetras genuinely captivating.

Understated Elegance in Motion

Unlike the bold primary colours of Neon or Cardinal Tetras, the Lemon Tetra offers a more refined, naturalistic beauty. The translucent yellow body, bright yellow fin edges, and distinctive red eye create a harmonious, warm-toned palette that pairs exceptionally well with lush green planting, driftwood, and natural hardscape. In a school of 10 or more, their synchronized movement adds a gentle, flowing energy to the mid-water zone.

Warm, golden, and quietly beautiful — the Lemon Tetra is the schooling fish that brings a gentle glow to the planted aquascape.
