General Description
Pethia punctata is a relatively unknown species in the aquarium trade, with a taxonomic history that has caused confusion among researchers. Belonging to the Cyprinidae family, it is classified under the order Cypriniformes and can grow up to 5.5cm in size. The species is distinguished by its two dark body blotches, complete lateral line with 27 scales, and a dorsal fin with rows of spots.
Aquarium Setup
When setting up an aquarium for Pethia punctata, it is recommended to provide a well-planted environment with a dark substrate and floating plants. The species thrives in a tank with mild water movement and appreciates driftwood to create a natural habitat. The water conditions should be maintained at a temperature between 21-26°C, pH range of 6.0-7.5, and hardness of 36-215ppm. For optimal care, a tank size of at least 90 litres is recommended.
Behaviour
Known for its peaceful nature, Pethia punctata is an ideal community tank member. When kept in a mixed-sex group of 8-10 individuals, the interaction between rival males becomes fascinating to observe. In competitive situations for female attention or hierarchical status, males exhibit their most vibrant colors.
Feeding and Diet
As an omnivorous species, Pethia punctata likely feeds on worms, insects, small invertebrates, plant material, and organic detritus in the wild. In captivity, they readily accept small live and frozen foods like bloodworms, Daphnia, and Artemia, alongside high-quality dried flakes and granules with additional plant or algal content.
Reproduction & Dimorphism
Reproduction methods for Pethia punctata are not extensively documented. However, similar species suggest that they are egg-scattering free spawners without parental care. Adult males are easily distinguishable from females by their slimmer bodies and more vibrant coloration, particularly evident in their unpaired and ventral fins.
Habitat and Distribution
Narayani is native to the Western Ghats mountain range in India, primarily inhabiting shallow streams and minor tributaries, often with mud or silt substrates. Its distribution extends across Kerala and Tamil Nadu, with possible occurrences in river systems of Karnataka. The species is versatile, adapting to various habitats with fluctuating water depth, flow, and turbidity.
