Emperor tetras are highly sexually dimorphic and thus males and females are quite easily distinguished from each other. The body is long, slim, and flattened to about 3 inches at maturity. Looking from the eye to the tail area, you will find a black line placed within a blue stripe. The sickled shaped dorsal fin, along with the pectoral fin and anal fins are yellow. The male is larger than the female and his anal fins are longer. The male caudal is more pointed than the female.
