Overview
Keep spotted barbs in a group of at least six in a tank of 150 litres or more, since they are active and commonly reach 12 to 15 cm. Water at 22 to 26 C with a pH of 6.0 to 7.0 and clean, moving conditions suits them. Feed flakes, pellets, vegetables, and frozen foods, as they are hearty omnivores. They are peaceful toward fish too large to eat but will bully small or slow tankmates, so choose robust company.
In the wild
The spotted barb is a widespread, adaptable fish found in streams, rivers, canals, and ponds across much of Southeast Asia. It forages actively over the bottom and in midwater in a range of conditions. Adults carry scattered dark spots and a blotch at the tail base on a stout silver body. It is a hardy, boisterous barb that grows larger than most community barbs.
Good to know
Formerly Puntius binotatus or Systomus binotatus, the species now sits in the genus Barbodes among the larger Southeast Asian barbs. It is so widespread and variable that it is treated as a species complex, with local forms differing in size and pattern. Wild fish can reach nearly 20 cm, though tank fish usually stay smaller.
Did you know
It is one of the most common wild fish across much of Southeast Asia and turns up in ricefield ditches and drains, which is part of why it is so hardy in the tank.
