Devario Affinis

Datasheet

General Description:The Devario Affinis, formerly considered synonymous with D. aequipinnatus, is a poorly-known species within the aquarium hobby. This fish is characterized by stripes on its body and fins, with specific designations such as P stripe, A stripe, and D stripe as per taxonomic studies by Blyth and Fang. The species falls under the Cyprinidae family and is part of the Cypriniformes order.

Aquarium Setup:For optimal care, a tank set up should consist of variably-sized, water-worn rocks, sand, fine gravel, and small boulders to mimic a flowing stream or river habitat. Driftwood, roots, or branches can be added, and hardy aquatic plants like Microsorum and Anubias species can be attached to the decor. Water conditions should be pristine, with a high oxygen content and moderate water movement. Regular water changes of 30-50% tank volume are recommended, and a secure cover is essential due to the species' jumping behavior.

Behaviour:The behavior of Devario Affinis is not extensively documented, but it is unlikely to exhibit aggression and should coexist well with similar-sized fish in natural environments. To encourage natural behavior and social interactions, it is advisable to keep a group of six or more in the aquarium.

Feeding and Diet:In the wild, Devario Affinis predominantly feeds on insects and their larvae and is expected to accept a varied diet in captivity. A quality dried food can serve as the staple diet, supplemented with small live or frozen foods such as bloodworms, Daphnia, and Artemia to enhance coloration and overall condition.

Reproduction & Dimorphism:Sexual dimorphism in Devario Affinis is noted in sexually mature females being rounder-bellied, less colorful, and slightly larger than males. Further details on their reproduction and breeding behavior are not readily available within the existing information.

Habitat and Distribution:The species is likely found in hill streams and upper reaches of small rivers with clear, well-oxygenated water, gravel substrates, and marginal vegetation. Devario Affinis is distributed in the region of Dawei District in southern Myanmar, particularly in rivers draining the western face of the Bilauktaung subrange of the Tennasserim Hills and the lower Salween river basin.
