Rosy Tetra XL – Hyphessobrycon rosaceus

Rosy Tetra XL, scientifically known as Hyphessobrycon rosaceus, is a graceful and colorful freshwater fish admired for its soft rosy-pink body, subtle red highlights, and elegant finnage. Native to South American river systems, this species is a favorite for aquarists seeking a peaceful yet visually appealing schooling fish.

The “XL” size refers to larger, more mature specimens, which display fuller body shape, deeper coloration, and more pronounced fin extensions. Males are particularly striking, often showing longer dorsal and anal fins, while females appear slightly rounder and softer in tone.

When kept in groups, Rosy Tetras create a calm and harmonious display, gliding gently through the mid-water level. Their soft coloration pairs beautifully with green plants, driftwood, and darker substrates, making them ideal for planted aquariums and aquascapes.
