Description
The Sucker-belly Loach is a unique freshwater fish known for its flattened body and modified fins that allow it to cling to rocks in fast-flowing streams. Its mottled coloration provides excellent camouflage, and its dorsal fin often features distinctive yellow and black markings. These peaceful bottom-dwellers are excellent algae grazers.
