Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); ottoschmidti: The specific name is given in honour of Otto Schmidt, a keen birder and fish enthusiast, for his long-time and significant contributions to the study of fishes of the genus Nothobranchius; a noun in genitive (Ref. 122068).
Eponymy: Otto Schmidt is a “keen birder and fish enthusiast”, who was honoured for “…his long-time and significant contributions to the study of fishes of the genus Nothobranchius.” He was co-collector of the type with EB Watters and B Cooper. (Ref. 128868), visit book page.

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 16 - 18; Anale stekels: 0; Anale zachte stralen: 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 (Ref. 122068). Furthermore, it differs from the other members of the Nothobranchius taeniopygus species group in central and western Tanzania by a head width 67-73% of head length vs. 54-66%; and caudal peduncle length 121-130% of its depth vs. 119% and 132-169% (Ref. 122068).
Found in seasonal pools and marshes (Ref. 122068).
