Iguanodectes spilurus, the green-line lizard tetra, sometimes referred to in retail stores as the slender tetra, is a small characiform fish from the rivers of South America. It is not a well-studied species, but research is available, including data from hobbyists who keep it as an ornamental fish. It has a distinct lateral stripe of reflective-green scales, and lacks any red markings therein; red is common in congeners' lateral stripes (and is thus a differentiating feature).
