Golden Mahseer

Tor putitora, the Golden Mahseer, is one of the most iconic fish of the Himalayan foothills, reaching over a metre in length in the wild and bearing spectacularly large, golden-orange scales that have made it a symbol of the rivers of northern India, Nepal, and Bhutan. It is critically endangered throughout its natural range due to overfishing, habitat destruction, and dam construction.

In an aquarium context, Tor putitora is a fish for very large specialist or public aquarium facilities only. It requires immense volumes of cold, highly oxygenated water, powerful filtration, and strong flow. Adult fish are gentle giants — peaceful, curious, and surprisingly interactive with their keepers — but their size requirements put them firmly beyond the scope of private hobbyist keeping for most individuals.

Conservation aquaculture of Tor putitora is undertaken by several institutions in South Asia, and captive-bred fingerlings from these programs represent the only ethically acceptable source for any aquarium display.

Water: Temperature 15–22°C, pH 7.0–8.0, GH 8–18; cold, fast-flowing, highly oxygenated water essential; chiller may be required in warmer climates. Tank: Minimum 2000 L public aquarium display; industrial sump filtration; very strong flow; no fragile décor. Feeding: Omnivorous; large pellets, fruits, earthworms, prawn, and vegetable matter; feed large amounts to support growth. Breeding: Conservation aquaculture programs in India and Nepal; not for private breeding attempts. Compatibility: Peaceful with other very large, robust fish; not suitable for standard community aquariums under any circumstances.
