Loaches are active, bottom-dwelling freshwater fish known for their elongated bodies and playful behaviour. Native to Asia and parts of Europe, they are popular in aquariums for their unique appearances and role as scavengers. Loaches thrive in groups and prefer soft substrates. An interesting fact is that some loaches, like the Clown Loach, can produce clicking sounds when feeding or interacting, adding a unique auditory element to your tank. They are omnivores, enjoying a diet of sinking pellets, live foods, and plant matter, making them a fascinating and engaging addition to any aquarium.
