亚马孙河矮丽鱼

<em>Nannacara adoketa</em> is a small freshwater cichlid of the family Cichlidae, native to river systems in South America. This species typically reaches a maximum length of approximately 4.9 cm. Members of the genus <em>Nannacara</em> are dwarf cichlids associated with the Amazon basin and surrounding drainages, often found in soft, acidic, black-water streams and small tributaries shaded by forest canopy. These environments are characterized by low conductivity, tannin-stained water, and leaf-litter substrates. <em>Nannacara adoketa</em> and its congeners typically feed on small invertebrates and microcrustaceans. Like many cichlids, members of this genus display notable parental care behaviors, guarding eggs and fry. Their small size and tolerance of soft water conditions have made related species popular in the aquarium hobby. Details of specific habitat associations and the precise geographic range of this species remain limited in the ichthyological literature.
