Researchers with the Dresden Museum in Germany have discovered and described a new species of tetra of the genus Hyphessobrycon. The fish, Hyphessobrycon clavatus was discovered in Peru. The diminutive fish measures just 1.1 inches in length and has a somewhat unique color scheme. The fish has a black stripe that covers most of the back of its belly and into the tail while the back is somewhat clear with a hint of gold fleck in a line that runs down its sides. The fins are clea but each has a white tip.
The body structure is similar to some of the more well known tetras in the hobby, including the neon and cardinal tetra as well as the glowlight tetra. These fishes sport longish and more streamlined bodies than other tetras, such as the black skirt tetra or rosy tetra.
