Cooper, renowned collector and breeder of killifish, for his significant contributions to the field study of Nothobranchius and to the killifish hobby in general; a noun in genitive (Ref. 117281).

خارهاي باله پشتي (کل) : 0; شعاع نرم باله پشتي (کل) : 14 - 16; خارهاي باله مخرجي: 0; شعاع نرم باله مخرجي: 14 - 16; مهره ها: 26 - 27. Diagnosis: Nothobranchius cooperi belongs to the Nothobranchius brieni species group (Ref. 117281). With the exception of N. rosenstocki and N. sainthousei, it is distinguished from all other species of that group by having broad orange, vs. red brown, posterior scale margins on the trunk and anal fin, with a uniform orange-red margin, vs. light blue, yellow, red-brown or black margin (Ref. 117281). It is distinguished from N. sainthousei by having an anal fin that is uniform orange-red with an irregular to regular, light blue-green zone close to the base, vs. orange-brown spots and orange-brown margin, and a wider, more prominent light blue marginal band to the caudal fin; head length 32.5-36.2% of standard length vs. 25.1-29.3%; prepectoral length 32.5-36.2% of standard length vs. 25.1-29.4%; and head width 70-77% of its depth vs. 79-86% (Ref. 117281). It is distinguished from N. rosenstocki by having a prepelvic length 48.8-51.9% of standard length vs. 45.1-49.0%; and a head depth 75-77% of head length vs. 78-84% (Ref. 117281). Furthermore, the species is characterised by a caudal peduncle length 1.2-1.3 times its depth, compared to 1.4-1.5 times in N. sainthousei, and 1.6 times in N. rosenstocki (Ref. 117281).
It is a micropredator, feeding on small aquatic crustaceans, worms, insect larvae and other zooplankton (Ref. 117281). The species appears to qualify as vulnerable (B1bii) according to IUCN criteria (Ref. 117281).
