Etymology: Sarotherodon: Greek, saros, -ou = sawdust + Greek, ther = animal * Greek, odous = teeth (Ref. 45335).
Eponymy: Gerhard Steinbach (1923–2016) was an entomologist at the Humboldt University of Berlin. He took part in the expedition, led by zoologist Martin Eisentraut (see Konia eisentrauti), during which the type was collected. (Ref. 128868), visit book page.

大小 / 重量 / 年龄
Maturity: Lm ? range ? - ? cm
Max length : 11.3 cm SL 雄鱼/尚未辨别雌雄; (Ref. 81260)
背棘 (总数) : 16 - 17; 背的软条 (总数) : 10 - 11; 臀棘: 3; 臀鳍软条: 8 - 10; 脊椎骨: 29 - 31. Diagnosis: 19-23 rakers on lower limb of first arch (Ref. 81260). Length of lower pharyngeal jaw 40-50% of head length (Ref. 81260), width 34.5-38.0 (Ref. 2). Pearly yellow in life, with no markings on body; preserved specimens dark grey on back, with a horizontal darker band in some; decurved snout (Ref. 2).
浅蓝灰色黄色活着时, 在身体上没有斑纹。 保存的标本深灰色的背面, 在一些里面具有一个水平的较黑的条纹。 向下弯曲的吻。 低咽骨长度 45-49.5% 头长，宽度 34.5-38.0.
Seems to prefer shallow areas near the edges of the lake (Ref. 52307). Occurs in schools at the surface; stomach of specimens which were examined contained organic debris; benthic and epilithic diatoms, and sponge spicules were nearly always present and many had inorganic particles in the stomach; individuals were seen shoveling sand into the mouth, moving it about in the buccopharynx, then spitting out the sand and making swallowing movements (Ref. 2). Lacks marked sexual dichromatism when sexually active (Ref. 81260). Probably a biparental ovophilic mouthbrooder that forms little to no (Ref. 52307) and only temporary pair bonds (Ref. 81260).
成群出现在水表面。 被检查到的标本的腹部包含了有机的残砾。 底栖与附在岩石上的硅藻 , 与海绵针状体几乎永远有，而且多数有了腹部的无机的粒子。 个体被见到铲沙子进入嘴巴,在 buccopharynx 中移动它到处, 然后唾吐出沙子与制造吞运动.(参考文献 2)
