Claves de identificación | Morfología | Morfometría
Gila elegans can be distinguished from similar species Gila cypha by having terminal mouth, angle along anal fin base continues well above caudal fin, more slender caudal peduncle, smaller hump on nape, usually dorsal fin with 10 rays; and 75-99 scales on lateral line. Breeding males with red lower side and pectoral and anal-fin bases (Ref. 86798).

Adults inhabit flowing pools and backwaters, usually over mud or rock. Streamlined body may suggest occasional occurrence in swift runs (Ref. 86798).
