White-finned gudgeon (Gobio albipinnatus)
Sand Pig fish (Gobio albipinnatus) is a small fish, with a length up to 12 cm. It has an elongated body, more cylindrical than other pig fish, a little compressed sideways, and a pair of mustache. The color is brown-gray on the back and white-yellow on the side, painted with seven up to nine large black spots, arranged from head to tail.
It lives in rivers in areas with fine sand or clay substrate and prefers places with deeper water and weak current, such as natural basins along the river.
The sand pig fish has an unfavorable (inadequate) conservation status, being a rare species whose areal is declining.
