Gymnostomus Ariza

Datasheet

General Description

Gymnostomus Ariza, commonly known as G. ariza, is characterized by its body adorned with thin stripes predominantly above the lateral line, sometimes showcasing a broader midlateral stripe in larger specimens. With 32-35 lateral scales, this species boasts 7-8/1/5-6 transverse scale rows and 8-9 branched dorsal-fin rays. Its coloration ranges from dull dirty white to greyish, silvery, or yellow, displaying a variable live pattern.

Aquarium Setup

When setting up an aquarium for G. ariza, it is important to mimic its natural habitat. Provide a tank with flowing water to mirror its preference for streams and tributaries. Ensure the water is clear and well-aerated. Decoration with rocks, driftwood, and live plants can help create hiding spots and enrich the environment. Refer to the appropriate water parameters in the table for ideal conditions for this species.

Behaviour

These fish are known to be active swimmers, especially in a well-structured aquarium environment. They may display shoaling behavior, so it is advisable to keep them in groups rather than solitary. G. ariza tends to explore its surroundings and may show territorial tendencies, particularly during breeding periods.

Feeding and Diet

In the aquarium, G. ariza can be fed a varied diet to ensure optimal health. They are omnivores, so offering a mix of high-quality flake food, pellets, live or frozen invertebrates, and vegetables is recommended. Regular feeding schedules and monitoring of appetite are essential for maintaining their well-being.

Reproduction & Dimorphism

This species naturally reproduces during the wet season, typically in temporarily flooded areas. In a captive setting, breeding can be induced through specific techniques. Dimorphism in G. ariza is not distinctly pronounced, though subtle differences in size and coloration between sexes may be observed during breeding stages.

Habitat and Distribution

Gymnostomus Ariza thrives in habitats characterized by flowing streams and tributaries with clear water, where it can forage and navigate efficiently. Widely distributed across the Indus basin, encompassing regions from Pakistan to Myanmar and various river drainages in India, including the Ganges-Brahmaputra, Krishna, and Cauvery systems. The species' resilience and adaptability to diverse aquatic environments contribute to its extensive distribution range.
