Kuhli Loach: these fun little fish have a long slender body that resembles an eel. From Indonesia they have a banded pattern of black and gold that really stands out! Nocturnal by nature they appreciate many available hiding places and sandy substrate. They max out at around 3”-4” making them a fantastic option for a peaceful bottom feeding in smaller tanks. #kuhliloach #loaches https://www.petzonesd.com/black-kuhli-loach/ | Pet Zone Tropical Fish, San Diego, California
