Dorsal spines (total): 0; Dorsal soft rays (total): 16 - 18; Anal spines: 0; Anal soft rays: 15 - 18. Diagnosis: Nothobranchius ottoschmidti is distinguished from all other species of the genus by the following characters in males: body colouration light blue to blue-green with red-brown to grey-brown scale margins; anal fin light brown to yellow-grey with irregular red-brown to brown spots proximally, followed by a narrow brown to red-brown submedial band, a slender cream, yellow or light brown medial band with red-brown spots on the membrane, and a broad black distal band; caudal fin light grey or brown with small red-brown spots proximally, a slender semi-translucent grey subdistal band and a narrow irregular dark grey to black dstal band; pelvic fin light blue-grey in basal zone, with broad yellow medial band and narrow black distal band .
