The torpedo barb grows quite large and is a very fast swimmer it likes lots of space to move and feels most at home in shoals of its own kind. Because of this we recommend at least a 4 foot tank for keeping them in with a volume of at least 250 Litres.
Given its natural habitat it’s best kept in a set-up dedicated to the replication of a flowing stream. Use a sand or gravel substrate, and scatter some smooth, water-worn rocks of varying sizes around the tank. An external canister or internal power filter with the outlet placed at the water surface aiming down the length of the tank would provide the desired high levels of oxygenation and flow. An additional powerhead could also be used if you wish or a rivertank manifold could be installed.
