Sucker Barb

About

The sucker barb (Barbichthys laevis) is a sizeable cyprinid from the river systems of Southeast Asia, ranging across the Malay Peninsula, Sumatra, Borneo, Java, and into the Mekong and Chao Phraya drainages. In the wild it moves between habitats with the seasons. Spending dry months in main river channels and spreading into floodplain streams and canals when the rains arrive. That kind of environmental flexibility hints at a fish that is adaptable, though it does not fare well in heavily impounded or stagnant water. In the aquarium it behaves much as you would expect from its wild life: a calm, bottom-oriented grazer that causes little trouble with tankmates. The diet is primarily plant-based, algae and phytoplankton make up the bulk of what it eats in nature, so offering a varied herbivore diet in captivity is important to keep it healthy long-term. Given that adults can reach close to a foot in length, a spacious setup is non-negotiable, and this is probably not a fish for anyone just starting out. But for a keeper with a roomy, well-filtered tank and some experience managing larger cyprinids, the sucker barb is a peaceful and interesting resident that does not demand much beyond space and greens.
