River Threadfin Paradiseus Catfish (Polydactylus macrophthalmus<\/em>)<\/strong><\/h3>\n

Overview<\/strong><\/h4>\n

The River Threadfin Paradiseus Catfish is a distinctive freshwater catfish known for its elongated body, thread-like barbels, and large expressive eyes. This nocturnal, bottom-dwelling species is an intriguing addition to larger aquariums, showcasing unique behaviour and gentle predatory instincts.<\/p>\n

Origin<\/strong><\/h4>\n

Native to Southeast Asia, inhabiting rivers, streams, and estuaries with sandy or muddy substrates. Prefers areas with slow to moderate flow and ample hiding spots.<\/p>\n

Feeding<\/strong><\/h4>\n

Carnivorous. Feeds primarily at night on small fish, invertebrates, worms, and high-protein sinking pellets. A varied diet of live, frozen, and prepared foods ensures optimal health.<\/p>\n

Tank Mates<\/strong><\/h4>\n

Best kept with medium to large, non-aggressive fish. Avoid very small fish or shrimp, which may be eaten. Suitable companions include large tetras, barbs, peaceful cichlids, and other bottom dwellers of comparable size.<\/p>\n

Aggression<\/strong><\/h4>\n

Generally peaceful toward similar-sized tank mates, but territorial over substrate and feeding space. May prey on smaller fish.<\/p>\n

Experience Level<\/strong><\/h4>\n

Intermediate to advanced. Requires a large, well-maintained aquarium with soft substrate and stable water conditions.<\/p>\n
