Etymology: Haplochromis: Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335); paradoxus: From the Greek 'paradoxos', meaning 'contrary to expectation, incredible'; the species name is a double entendre, in reference to the strange appearance of the fishes, especially their strongly oblique gape and lower jaw, and to their seemingly paradoxical zoogeographical situation (Ref. 51927).

背棘 (總數) : 14 - 16; 背的軟條 (總數) : 9 - 11; 臀棘: 3; 臀鰭軟條: 8 - 9; 脊椎骨: 29 - 30. Diagnosis: Haplochromis paradoxus differs from all known paedophagous species of Haplochromis of the Lake Edward system by its more numerous outer teeth, 36-65 vs. 16-35, that are strongly recurved and closely set in long tooth bands (Ref. 127594). It is further distinct from H. gracilifur and H. molossus by a longer snout, 28.7-36.0% of head length vs. 24.0-26.7% and 25.1-30.7%, respectively, and longer head, 32.2-36.2% of standard length vs. 29.8-30.7% and 29.5-32.0%, respectively (Ref. 127594). It differs from H. taurinus by its smaller eyes, 25.3-32.1% of head length vs. 32.9-40.2%, and from H. relictidens by its more slender head, 41.7-51.2% of head length vs. 47.7-54.7% (Ref. 127594). Mature males dorsally grey to bluish and ventrally intense yellow vs. different colour patterns in other paedophages (Ref. 127594). Haplochromis paradoxus can be distinguished from piscivorous sensu stricto species from Lake Edward system by its small teeth with very strongly recurved necks and short, bluntly pointed, and usually weakly tricuspid crowns vs. larger, straight to recurved, and acutely pointed teeth in piscivores; its lips are slightly thickened, and its maxillae reach posteriorly before vertical through anterior edge of eyes vs. lips are not thickened and maxilla generally exceed this point in piscivorous species (Ref. 127594). It's a haplochromine species with a strongly oblique gape and lower jaw, in connection with a pronounced concavity in the outline of the head in front of the eye (Ref. 51927). It is distinguished from members of the genus Pyxichromis by a lower body depth, 31.5-33.5% of standard length vs. 35-42%; a lower cheek, 20-24% of head length vs. 24-32%; and the dentition of the oral jaws consisting of bicuspid and tricuspid teeth in both jaws (Ref. 51927).
Body shape (shape guide): fusiform / normal.
一個單色的種具有一個極傾斜口裂與下頜, 在連接中在眼睛前方中的頭部的輪廓中具有一個明顯的凹窪.(參考文獻 51927) 它是雙顎內與包含二頭齒與三尖齒的一個身體下半部深度 (31.5-33.5% SL vs.35-42), 一個低的頰 (20-24% HL vs.24-32) 與口部顎的生齒的本屬 Pyxichromis 的其他成員區分。 (參考文獻 51927) 身體中等細長的.(參考文獻 51927) 吻部的背面接近水平的.(參考文獻 51927) 嘴 isognathous; 唇些微地粗的。 (參考文獻 51927) 縱向的線鱗片: 32-33,20-21個上面的側線鱗片與 10-12 中央側線鱗片.(參考文獻 51927) 頭部的側線孔不被增大, 在眶下骨與淚骨上的孔一般增大了。 (參考文獻 51927) 鰓蓋除了鰓蓋斑塊以外完全覆蓋著鱗片, 鱗片圓形的.(參考文獻 51927)
