Cherry Barb Care


Where Do Cherry Barb From?

Cherry Barbs (Puntius titteya) hail from the freshwater rivers and streams of Sri Lanka. These waterways are teeming with vegetation, providing a perfect environment for the fish to thrive.

Known for their durability, Cherry Barbs have adapted well to various water conditions in their natural habitat. They were first described scientifically in 1929.

In the wild, these fish are often found in shaded areas with plenty of hiding spots amongst plant life and submerged roots. This environment mimics the thick vegetation you might want to emulate in their aquarium setup.

Initially introduced to the aquarium trade in the 1930s, Cherry Barbs have since become a popular choice for aquarists worldwide. Their vibrant colors and ease of care make them a staple in many home aquariums.


What Is the Natural Habitat of a Cherry Barb?
