Also known as the Spanner Barb, the T-Barb originates in Asia where it can be found in Thailand, Malaysia, Sumatra, Borneo and Singapore. These fish predominantly inhabit hill streams and pools that form at the bottom of waterfalls but they can also be found in wide, slow-flowing rivers and blackwater streams. This species is one of the larger species of Barb, typically achieving a maximum height around 7 inches. Due to their size, these fish should not be kept with smaller, more timid species.
