Etymology: Sarotherodon: Greek, saros, -ou = sawdust + Greek, ther = animal * Greek, odous = teeth (Ref. 45335).
Eponymy: Karl Lohberger was (probably) Holly’s colleague at Naturhistorisches Staatsmuseum (Vienna). He published six papers on fishes (1929–1930) and then seems to have dropped from the ichthyological record. He named a barbel after Holly. (Ref. 128868), visit book page.

背棘 (總數) : 15 - 17; 背的軟條 (總數) : 10 - 12; 臀棘: 3; 臀鰭軟條: 8 - 10; 脊椎骨: 29. Diagnosis: 14-18 rakers on lower limb of first arch; 30-31 scales in lateral line (Ref. 81260). Body silver-grey, with mid-lateral black band interrupted anteriorly on caudal peduncle (Ref. 2, 81260). Head length 33.0-38.4% of standard length; jaw teeth with slender shafts and broad crowns (Ref. 81260). Mature fishes of both sexes with variable black areas on lower jaw and lower parts of head; no tilapia-mark (Ref. 2).
銀灰色; 側面中央的黑色斑紋在尾柄的前部上中斷。 兩性的成熟魚在下頜與頭部下半部上有多變的黑色區域。 沒有吳郭魚-標誌。
Found throughout the lake, but seems to prefer zones with submerged wooden or stone structures (Ref. 52307). Usually forms schools at the surface; feeds mainly on epiphytic and epilithic filamentous algae, and the diatoms, rhizopods, rotifers and organic debris found among them; adults feed by opening their mouths very wide and applying them to the surface of the rock as though sucking the material in (Ref. 2). Lacks marked sexual dichromatism when sexually active (Ref. 81260). Both sexes are possible incubators (Ref. 52307). Forms temporary pair bonds (Ref. 81260), for the entire duration of incubation/broodcare (Ref. 52307).
通常形成魚群在水表面。 主要吃附生植物而附在岩石上的菌絲藻，而且矽藻，根足類動物, 輪蟲與有機的殘礫發現於他們中了。 好像吸材料進入，成魚藉著非常廣闊地打開他們的嘴和應用他們到岩石的表面覓食。 (參考文獻 2)
