Consigli per l'identificazione
Size
Adults rarely exceed 2.5 cm (1 inch) in total length, making them one of the smallest percoid fish.
Coloration (Males)
The intense scarlet-red body with distinct iridescent blue-green vertical bars is a key identifier for males. No other Badis species exhibits this exact pattern and color intensity.
Fin Extensions (Males)
Mature males develop noticeably extended rays in their dorsal and anal fins, which are often tipped with blue-green.
Body Shape
Their relatively deep, laterally compressed body distinguishes them from more elongated micro-fish.
Habitat
- Tipo di acqua
- freshwater
- Profondità
- Shallow, typically less than 1 meter
- Ambiente
- Slow-moving or stagnant clear waters of small streams, rivulets, ponds, and ditches, often heavily vegetated with aquatic plants and leaf litter. They prefer areas with dense cover.
- Areale geografico
- Endemic to parts of India, specifically the states of West Bengal and Assam, and potentially parts of Bangladesh. Found in the Brahmaputra River basin and its tributaries.

Fatti chiave
Smallest Percoid Fishamazing
Dario dario is considered one of the smallest known percoid fish species, rarely exceeding 2.5 cm in length.
Territorial Displaysbehavior
Despite their tiny size, male Scarlet Badis engage in elaborate territorial displays, flaring their fins and intensifying their colors to ward off rivals.
Micro-predatorbehavior
Their diet consists exclusively of tiny live or frozen invertebrates, making them obligate micro-predators.
Bubble Nestsbehavior
Unlike many other anabantiforms, Dario dario males do not build bubble nests. Instead, they typically spawn on flat surfaces like leaves or rocks.
Sexual Dimorphisminteresting
The striking difference in coloration and finnage between males and females is a prime example of sexual dimorphism in fish.
