Sailfin Catfish

Leiarius pictus hails from the upper Amazon basin and shares the genus's defining tall dorsal fin, though its pattern differs markedly — a pale cream body covered in bold dark spots gives it a distinctly leopard-like appearance. It is somewhat smaller than L. marmoratus, making it marginally more manageable.

Like its congener, L. pictus is an omnivore and accepts a varied diet. It is an active fish that patrols its territory confidently, particularly at night. The dorsal fin spine is sharp and can deliver a painful puncture if the fish is handled carelessly during maintenance.

The species is periodically available through specialist importers and commands a premium due to its relatively limited export. In well-maintained large aquaria it is long-lived and becomes a genuinely impressive showpiece fish.
