Iguanodectes spilurus (Günther, 1864)

Source-backed taxonomic record

Accepted species in Catalogue of Life’s 11 September 2026 base release. This preserves the source classification and available supporting data; it is not a completed species monograph.

Open encyclopedia reference

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).

For a time, researchers had uncertainties regarding the taxonomic status of I. spilurus. It was originally named as a member of sister genus Piabucus, and then was described with the name I. tenuis. However, its modern placement as a member of Iguanodectes with specific name spilurus is generally accepted by the scientific community.
