阿氏蜥形脂鯉

<em>Iguanodectes adujai</em> is a small freshwater fish of the family Iguanodectidae, a neotropical family of characiform fishes found in river systems of South America. This species typically reaches a maximum length of approximately 6.2 cm. Members of the genus <em>Iguanodectes</em> are slender, laterally compressed fishes associated with the diverse freshwater ecosystems of the Amazon and Orinoco basins, often inhabiting clear-water or black-water streams and rivers with sandy substrates and abundant riparian vegetation. These characiforms typically form schools and are believed to feed on small invertebrates, plant matter, and fallen fruits and seeds near the water surface. The family Iguanodectidae is notable for including fishes that often display sexual dichromatism or distinctive coloration patterns. Details of the specific habitat preferences and precise geographic range of <em>Iguanodectes adujai</em> remain limited in the ichthyological literature.
