Dwarf Gudgeon

This fish bears resemblance to the goby minnow, but is distinguished by its somewhat stumpy head. Its body is slender and elongated, approaching a cylindrical shape, yet it is slightly flattened vertically. The belly is flat. In comparison to the common gudgeon, both the head and snout are shorter. Notably, the snout is short, blunt, and concave on the dorsal side.
