Schistura Devdevi

Datasheet

General Description

The Saddleback Loach is a species within the Nemacheilidae family and is commonly known for being collected for the aquarium trade, sometimes referred to as the 'firefly loach.' It belongs to the Schistura genus, which is the most species-rich among nemacheilid loaches with approximately 190 members. These loaches typically have dark bodies with regular bars, a caudal-fin base black bar, and display clear sexual dimorphism in some species. They are often found in flowing streams or areas close to waterfalls, with some even being cave-dwelling and blind.

Aquarium Setup

Setting up an aquarium for the Saddleback Loach involves creating an environment that resembles a flowing stream or river. This includes using a substrate of rocks, sand, fine gravel, and water-worn boulders. Driftwood branches can be added to create hiding spots and broken lines of sight. While most aquatic plants may struggle in such conditions, hardy varieties like Microsorum, Bolbitis, or Anubias species can be grown attached to the decor. It is essential to maintain high levels of dissolved oxygen with some water movement in the tank, achieved through power filters, additional powerheads, or airstones. Clean water is crucial for the loach's well-being, requiring regular 30-50% water changes weekly.

Behaviour

In a community aquarium, the Saddleback Loach is unlikely to exhibit aggression towards tankmates if selected with care. Fish species that inhabit similar biotopes, such as Danios, Rasboras, and Puntius, can make good companions for the loach. The presence of other schooling fish can boost the confidence of benthic species, contributing to a harmonious tank environment.

Feeding and Diet

Being omnivorous, the Saddleback Loach primarily feeds on small insects, worms, crustaceans, and zooplankton in its natural habitat. In captivity, it accepts dried foods but should not be fed exclusively on these. Offering daily meals of live and frozen foods like Daphnia, Artemia, and bloodworms will help maintain its coloration and overall condition.

Reproduction & Dimorphism

The Saddleback Loach exhibits clear sexual dimorphism in some species. Reproduction in captivity is possible under suitable conditions, although specific details about their breeding behavior and characteristics are not provided in the available information.

Habitat and Distribution

This species is native to the upland regions of Assam, Sikkim, Arunachal Pradesh, and West Bengal states in northern India. It is typically found in smaller, well-oxygenated streams with clean flowing water, gravel substrates, and rocks. The Saddleback Loach is also believed to potentially occur in Bhutan, with its type locality being the Eastern Himalayas in India. An accurate distribution record from Nepal is awaiting confirmation.
