Description
Hoplias macrophthalmus, commonly known as the Largescale Robber, is a large, predatory freshwater fish native to South America. It is characterized by its robust, torpedo-shaped body, large scales, and powerful jaws, making it a formidable hunter in its natural habitat. This species is highly territorial and aggressive, requiring a species-specific tank or very carefully selected, equally large and robust tankmates.
