Etymology: Aphyosemion: Greek, aphye, -es, sardine, anchovy + Greek, semeion = mark, signal (Ref. 45335);  grelli: The species is dedicated to the late Wolfgang Grell, member of the DKG (German Killifish Association); a talented killifish collector, breeder, and photographer who only one year before his death in May 2001, directed Eberl's attention to the probable existence of an unknown species in the area east of Sindara (Ref. 94461).

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 10-12; Anal spines: 0; Anal soft rays: 13 - 14. Diagnosis: Aphyosemion grelli is distinguished from all congeners by possessing a unique colour pattern of the unpaired and pelvic fins in females consisting the combination of a yellow basal portion and greyish to dark grey broad margin vs. never a similar colour pattern (Ref. 94461). Males are similar to Aphyosemion congicum, A. labarrei, A. ocellatum, A. passaroi, and A. teugelsi and distinguished from all other species of the genus by having black margins on their unpaired fins vs. never a similar colour pattern (Ref. 94461). Aphyosemion grelli differs from A. congicum males by the blue-green body and head colouration vs. orange; by the rounded dorsal and anal fins vs. pointed; by a horizontal series of densily set dots on flank vs. a few, larger and sparsely set dots; by a thin black distal margin on dorsal fin vs. dorsal fin almost completely black; by the rounded caudal fin vs. caudal fin pointed dorsally and ventrally; and by 11-12 dorsal-fin rays vs. 9-10 (Ref. 94461). Aphyosemion grelli differs from males of A. labarrei by a horizontal series of dots on flank vs. a dense pattern of large red blotches forming fused, irregular bands on caudal fin; by the rounded caudal fin vs. pointed dorsally and ventrally; by 10-12 dorsal-fin rays vs. 12-14; by 13-14 anal-fin rays vs. 14-17; and by 12 circumpeduncular scales vs. 13-14 (Ref. 94461). Aphyosemion grelli differs from males of A. ocellatum by a horizontal series of dots from humeral to caudal-fin base vs. single blue broad rounded blotch at humeral region; by the more anterior insertion of dorsal fin relative to anal-fin origin (D/A 6-7 vs. D/A 8-9); and by 13-14 anal-fin rays vs. 15-16 (Ref. 94461). Aphyosemion grelli differs from males of A. passaroi by the presence of a horizontal series of dots on flank vs. absence or a more irregular pattern of a few smaller dots on flank; by caudal fin with narrow black dorsal and ventral distal margins vs. broad black band along entire margin of caudal fin; by anal fin without any spots vs. with a pattern of red dots; and by 13-14 anal-fin rays vs. 15-16 (Ref. 94461). Aphyosemion grelli differs from males of A. teugelsi by the light pectoral-fin margin vs. dark; rounded dorsal and anal fins vs. pointed; by 16-18 pectoral-fin rays vs. 14-15; by 28-32 caudal-fin rays vs. 23-25; and by 9-10 scales on transverse series vs. 7-8 (Ref. 94461).

Biology     Glossary (e.g. epibenthic)

Aphyosemion grelli was found in a stream no wider than 1 m with a depth less than 40 cm; with small unidentified Barbus species as the only other fish present (Ref. 94461).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
