Log sucker
Extracted from the Wikipedia article Garra.
Garra is a genus of fish in the familyCyprinidae. These fish are one example of the "log suckers", sucker-mouthedbarbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 160 species of garras are native to Asia, but about one-fifth of the species are from Africa (East, Middle and West, but by far the highest species richness in Ethiopia).
