Sperata Bagrid

Sperata seenghala is a large and commercially important bagrid catfish found across the Indus and Ganges river systems of India, Pakistan, and Bangladesh. It is a significant food fish and one of the largest freshwater catfish of the Indian subcontinent, capable of reaching one metre in length in mature rivers. Its heavy, streamlined body, broad head, and large adipose fin give it a formidable and elegant appearance.

In the aquarium, Sperata seenghala is an impressive but demanding species requiring very large accommodations — 800 litres or more for long-term maintenance. It is a strong swimmer and active predator that needs powerful filtration, excellent water quality, and a protein-rich diet. Young specimens are more manageable and can be housed in progressively larger tanks as they grow.

This species is aggressive toward fish of smaller size and should be kept only with very large, robust companions such as arowanas, large cichlids, and other large catfish. Its imposing size, powerful swimming, and long lifespan make it a serious responsibility that is best left to experienced specialist fishkeepers with the facilities to match its requirements.

Water: 18–28°C, pH 6.5–8.0, soft to hard (GH 5–20); strong filtration and oxygenation essential. Tank: 800 L minimum for adults; very powerful filtration; minimal decor to allow free swimming. Feeding: Whole fish, large prawns, earthworms, fish fillet; feed 2–3 times weekly. Breeding: Not achieved in home aquaria; migratory seasonal spawner in large river systems. Compatibility: Aggressive; house only with very large robust species; will consume medium-sized fish.
