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).
Inhabits flowing pools and backwaters, usually over mud or rock. Streamlined body may suggest occasional occurrence in swift runs (Ref. 86798).
棲息於流動的潭水與洄水區, 通常在泥或岩石上面。 流線型的身體意味著至少迅急小支流的偶然職業。
