Etymology: Orthochromis: Greek, ortho = straight + Greek, chromis = a fish, perhaps a perch (Ref. 45335); gecki: The species is named in honour of Mr. Jakob Geck who is a passionate, German fish naturalist, thanking him for his dedicated volunteer work and untiring support for the ichthyology section of the ZSM; his great experience in keeping rheophilic cichlids contributed to the knowledge of behaviour and ecology of many cichlid taxa, including Orthochromis katumbii and O. indermauri (Ref. 122085).

توصيف مختصر
ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل): 16 - 17; شعاع نرم باله پشتي (کل): 10-12; خارهاي باله مخرجي 3; شعاع نرم باله مخرجي: 8 - 9; مهره ها: 29 - 31. Diagnosis: Orthochromis gecki can be readily distinguished from all species currently placed in Orthochromis, except O. torrenticola, which has eggspot-like maculae, by presence of eggspots on anal fin (Ref. 122085). It is further distinguished from O. kasuluensis by having fewer anal-fin rays, 8-9 vs. 10; from O. malagaraziensis by having more scales between upper lateral line and dorsal-fin origin, 5-8 vs. 3-4; from O. mazimeroensis by having more horizontal line scales, 29-31 vs. 26-28; from O. rubrolabialis, O. rugufuensis and O. uvinzae by having fewer anal-fin spines, 16-17 vs. 18-20, and in position of pterygiophore supporting last dorsal-fin spine, vertebral count 15-16 vs. 17-19; it is furthermore distinguished from O. uvinzae by having fewer abdominal vertebrae, 13-14 vs. 15-16, and by position of pterygiophore supporting last anal-fin spine, vertebral count 14-15 vs. 16-17 (Ref. 122085). Orthochromis gecki is distinguished from O. stormsi by having more horizontal line scales, 29-31 vs. 26-28, and fewer total gill rakers, 9-12 vs. 13-15; from O. polyacanthus by having fewer dorsal-fin spines, 16-17 vs. 18-20, more dorsal-fin rays, 10-12 vs. 8-9, and it is distinguished by position of pterygiophore supporting last dorsal-fin spine, vertebral count 15-16 vs. 17-18; from O. torrenticola by having fewer anal-fin spines, 3 vs. 4 (Ref. 122085). Meristic values of O. gecki overlap with those of O. luongoensis, O. kalungwishiensis, and O. machadoi but is distinguished by narrower interorbital width, 9.62-12.86% of head length vs. 13.18-21.27% (Ref. 122085). It is distinguished from Schwetzochromis neodon by having more circumpeduncular scales, 16 vs. 12; from Haplochromis snoeksi by having more anal-fin rays, 8-9 vs. 5-6; from Haplochromis bakongo by more horizontal line scales, 29-31 vs. 26-28, more dorsal-fin spines, 16-17 vs. 15, and by position of pterygiophore supporting last dorsal-fin spine, vertebral count 15-16 vs. 13-14; from Haplochromis moeruensis by having more horizontal line scales, 29-31 vs. 27-28, and more scales in upper lateral line, 21-25 vs. 19-20; meristic values of Orthochromis gecki overlap with those of Haplochromis vanheusdeni but is distinguished by having a smaller interorbital width, 9.62-12.86% of head length vs. 14.20-20.30% (Ref. 122085). It is distinguished from O. kimpala by having fewer series of scales on cheek, 0-2 vs. 3-4; meristic values of O. gecki overlap with those of O. mporokoso, O. katumbii, and O. indermauri but is distinguished by having smaller interorbital width, 9.6-12.9% of head length vs. 13.0-21.7% (Ref. 122085).
Found in a river which has a rocky bottom with patches of gravel and sand, and is about 15 meters wide and about 50 cm deep (Ref. 122085). This species seems to be a maternal mouthbrooder (Ref. 122085).
