Overview
The shovelmouth barb is a heavy, mostly peaceful river barb for a pond or show tank rather than a living-room setup. It is a fish for experienced keepers.
Did you know
The shovelmouth barb's scientific name comes from a local Bengali name, chaguni. Both the species and its whole genus, Chagunius, still carry that borrowed name.
Caring for the shovelmouth barb
Keep shovelmouth barbs in a group, since they shoal in the wild and really want numbers. Plan on at least 317 gal (1,200 L), and a proper group needs far more. They patrol the middle and lower water and need long, open, current-swept space.
Give them strong current, a bed of rock and gravel, and lots of open water. Keep the water at 61 to 79°F (16 to 26°C), cooler in winter, with a pH of 6.5 to 7.8. Keep oxygen and turnover high.
Feed meaty and vegetable foods on the bottom, such as large sinking pellets, prawn, mussel, earthworms and blanched greens. The shovelmouth barb is mostly peaceful for its bulk and will not hunt tank mates it cannot swallow. It dwarfs ordinary community fish, so companions must be large, calm and coolwater-tolerant.
Breeding males develop a mask of nuptial tubercles that densely covers the snout and cheeks. Shovelmouth barbs spawn in rivers and are not bred in home aquariums.
Good to know
Chagunius chagunio is a large member of the carp family, Cyprinidae. Francis Hamilton recorded it in his 1822 account of the fishes of the Ganges.
In the wild
The shovelmouth barb lives in the Ganges and Brahmaputra drainages of India and Nepal. It holds deeper, well-oxygenated runs of foothill rivers that stay cool for much of the year.
