Overview
The Sondhi danio is a brisk, peaceful schooling fish for a cooler-running community tank. It is easy to keep.
Did you know
The Sondhi danio shares its plateau with a lake full of one-of-a-kind fishes. Inle's basin is Myanmar's Galapagos, and this danio is part of the cast.
Caring for the Sondhi danio
Keep Sondhi danios in a group of eight or more, in a tank of 24 gal (90 L) or larger. Give them open swimming length and moderate flow.
Keep the water at 68 to 79°F (20 to 26°C) and a pH of 6.8 to 7.8. They are unfussy eaters and take flake, granules and small frozen foods.
Sondhi danios are peaceful toward their tank mates. For a coherent regional tank, pair them with other fish of the Inle plateau, such as the sawbwa barb and Inle loach. They scatter their eggs and do not guard them.
Good to know
The Sondhi danio, Devario sondhii, is a member of the family Danionidae. It carries a fine horizontal line along a pale body. Its restricted plateau range makes it uncommon in the trade.
In the wild
The Sondhi danio comes from the waters of the Shan Plateau around Inle Lake in Myanmar. At that altitude, the water runs cooler and harder than in lowland tropical streams.
