🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 12; Anal spines: 0; Anal soft rays: 14 - 16. Diagnosis: Males of Aphyosemion cryptum are distinguished from all other Aphyosemion, except for A. coeleste, by its unique combination of colouration characters in males: a light blue body with a few red markings on flanks and caudal peduncle; yellow to orange on distal part of unpaired fins; base of dorsal and anal fins blue, distally followed by a red band, two parallel or converging red lines along the blue centre of caudal fin; at least in anal and ventral part of caudal fin between red band and yellow to orange distal parts a narrow white line; by mitochondrial DNA results and male colour pattern it clearly belongs to the A. coeleste group . It differs from A. coeleste by the lack of a green or yellow iridescent blotch posterior to the operculum; in A. coeleste three to four less regular rows of red spots on anterior part of side within the green or yellow blotch vs. rows of red spots absent or reduced to a few irregular spots in A. cryptum .Cross section: oval.
