About

Osteoglossum bicirrhosum, the Silver Arowana, is one of the most iconic large freshwater fish. Its elongated, silvery body with large reflective scales and two prominent chin barbels give it a dragon-like appearance. A surface predator that leaps from the water to catch insects, birds, and small mammals from overhanging branches in the Amazon. Grows to 90+ cm and requires massive tank space. Prized as a good luck symbol in Asian culture. Sold at 12–15 cm juvenile size.

Care Guide

500+ L for adults — minimum tank width equals fish length. Ultra-secure lid — incredible jumper up to 2 m. Temperature 24–30 °C, soft slightly acidic water. Feed floating carnivore pellets, live/frozen fish, crickets, earthworms. Solitary — one per tank. Peaceful with fish too large to swallow.
