Mesonauta acora

<em>Mesonauta acora</em> is a freshwater cichlid of the family Cichlidae, native to South American river systems. This species typically reaches a maximum length of approximately 7.1 cm. Members of the genus <em>Mesonauta</em>, commonly known as festivum cichlids or flag cichlids, are recognizable by their distinctive body markings and elongated dorsal fin rays. They generally inhabit slow-moving or still waters in flooded forests, backwaters, and the margins of larger river channels, often associated with dense aquatic or marginal vegetation. <em>Mesonauta acora</em> is believed to occupy similar habitats within its range in the Amazon basin region of South America. The species is omnivorous, feeding on small invertebrates, plant matter, and organic detritus. Details of specific habitat associations and the precise geographic range of this species remain limited in the ichthyological literature.
