Dawkinsia Tambraparniei

Datasheet

General Description

The Dawkinsia Tambraparniei, also known as the 'Arulius' Barb, was originally classified as a subspecies of Dawkinsia arulius. It is a schooling species by nature and is ideally maintained in groups of 8-10 specimens. This fish species is a peaceful addition to a community aquarium, particularly when paired with other riverine species and bold, larger fish that are not intimidated by its active nature.

Aquarium Setup

Setting up the aquarium for the Dawkinsia Tambraparniei involves creating an environment that resembles a flowing stream or river. Utilizing a substrate of water-worn rocks, sand, fine gravel, and driftwood, along with hardy aquatic plants such as Microsorum or Anubias, can mimic its natural habitat. Regular water changes of 30-50% tank volume are recommended to ensure spotless water quality, as the species requires clean conditions to thrive.

Behaviour

Being a schooling species, the Dawkinsia Tambraparniei displays less skittish behavior when maintained in larger numbers. Aggressive behavior is generally contained within the group dynamics as males focus on establishing and maintaining their hierarchical positions. Thorough research is essential to select compatible tank mates to avoid conflicts within the community.

Feeding and Diet

In nature, the Dawkinsia Tambraparniei is considered a foraging omnivore, feeding on a variety of worms, insects, crustaceans, and plant material. In an aquarium setup, they readily accept a balanced diet of small live and frozen foods like bloodworms, Daphnia, and Artemia, alongside high-quality dried flakes and granules, ensuring optimal condition and vibrant colors.

Reproduction & Dimorphism

This species reproduces as an egg-scattering free spawner without parental care in the aquarium. To maximize fry production, a separate breeding tank with dim lighting and suitable substrate for egg collection is recommended. Adult males develop filamentous rays in the dorsal fin, exhibit vibrant coloration, and display tubercles on the head during spawning. Adult females are slightly larger, heavier, and less colorful than males.

Habitat and Distribution

The Dawkinsia Tambraparniei is native to the middle parts of the Tambraparni River basin in southern India. Originating from the Western Ghats mountains, this pelagic, riverine species inhabits habitats prone to fluctuations in water depth, flow, and turbidity during monsoon seasons. Many of these fish available in the aquarium trade are likely commercially bred specimens.
