Platinum Lapis Tetra (Hyphessobrycon cyanotaenia)

Platinum Lapis Tetra — Hyphessobrycon cyanotaenia

Icy silver flash with sapphire undertones

The Platinum Lapis Tetra is a refined and luminous South American schooling fish known for its cool metallic sheen. This platinum variation enhances the species’ natural silvery-blue tones, creating a polished, almost mirror-like body with subtle sapphire undertones along the lateral line. Under proper lighting, the scales shimmer with a crisp, icy glow that intensifies when the fish moves in groups.

Native to Amazonian tributaries, Hyphessobrycon cyanotaenia thrives in calm, well-maintained freshwater systems. Like most tetras, it is a true schooling species — best appreciated in coordinated groups that glide through midwater in synchronized motion. The platinum morph adds an elevated, high-end aesthetic to planted aquariums or peaceful community displays.

Growing to approximately 1.5–2 inches, the Platinum Lapis Tetra is compact yet visually striking, making it ideal for medium-sized aquariums focused on movement and shimmer.
