Clown loaches (Chromobotia macracanthus) are a popular species of freshwater tropical fish that are native to the rivers and streams of Southeast Asia, particularly Borneo and Sumatra. They are part of the loach family, and are also sometimes known as tiger loaches or polka-dot loaches.
These fish are characterized by their bright orange coloration, covered in a pattern of black stripes or spots. They have elongated bodies that can grow up to 12 inches (30 cm) in length, and long whisker-like barbels on their faces that they use to search for food.
Clown loaches are a peaceful species that are best kept in groups of five or more. They are active swimmers and enjoy having plenty of space to explore and hide. They prefer a heavily planted tank with plenty of hiding places and a sandy or fine gravel substrate. They are omnivores and will eat a variety of foods, including pellets, flakes, and frozen or live foods.
Clown loaches are known for their playful personalities, and they are often seen engaging in "shoaling" behavior, where they swim together in a group. They are also known to make a distinctive "clicking" sound that they use to communicate with one another. Overall, clown loaches are a fascinating and engaging species that can make a great addition to a community aquarium.
