🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 17; Anal spines: 0; Anal soft rays: 15 - 17. Diagnosis: Nothobranchius skeltoni is distinguished from all other species of the genus by the following characters in males: body colouration light blue with grey to brown scale margins; anal fin grey to red-grey with irregular dark grey spots proximally, followed by a broad dark red to maroon medial band, a narrow light grey subdistal band, and a broad black distal band; caudal fin light grey with slender semi-translucent dark grey distal band; pelvic fins light blue-grey, with broad dark red to maroon medial band and narrow black distal margin . Furthermore, it differs from the other members of the Nothobranchius taeniopygus species group in central and western Tanzania by a body depth at pelvic-fin origin 26.3-30.0% of standard length vs. 30.3-37.6%; suborbital depth 15-22% of head length vs. 23-31%; caudal peduncle depth 11.8-12.9% of standard length vs. 12.9-16.8%; and caudal peduncle length 160-169% in its depth vs. 119-151% . : fusiform / normal; Cross section: compressed.
