Etymology: Pachypanchax: Greek, pachys = fat + Panchax, a word created by Meinken in 1932 word created by Meinken in 1932; varatraza: Named for the Malagasy word varatraza, meaning east wind, in acknowledgement of the unanticipated presence of a Pachypanchax species in rivers draining the eastern slope of The Tsaratanana Massif (Ref. 57724).

簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 11-13; 臀鰭軟條: 17 - 19. Distinguished from Pachypanchax playfairii in lacking raised dorsolateral squamation and in details of its color pattern. Males without rows of discrete red dots on the flanks and red edging to the vertical fins; female lack any sort of black markings on the dorsal fin. Has the shortest pectoral fins (13.4% SL) among Malagasy Pachypanchax. Differs from Pachypanchax sakaramyi and Pachypanchax sparksorum by the absence of pectoral scales of reduced size. Can be distinguished from Pachypanchax omalonotus by the rounded dorsal and anal fins of males and their lack of discrete metallic gold spangling on the flanks; and also differs from the remaining Malagasy congeners by lack of iridescent white edging to, or darker submarginal banding on, the vertical fins (Ref. 57724).
在缺乏凸起的背外側的鱗片排列中與 粗背鮰〔Pachypanchax playfairii〕 區分了與詳細地它的彩色斑紋。 沒有列的雄性在側面與紅色的邊緣到垂直的鰭上不連續的紅色點; 在背鰭上的雌性的缺乏任何種黑色的斑紋。 有在 Malagasy Pachypanchax 之中的最短的胸鰭 (13.4% SL) 。 有別於 薩氏粗背鮰〔Pachypanchax sakaramyi〕 與 Pachypanchax sparksorum 縮小的藉由缺少胸鱗片。 能被在側面上金光閃爍的雄性與他們的缺乏不連續的金屬黃金的圓形背鰭與臀鰭與 扁粗背鮰〔Pachypanchax omalonotus〕 區分; 以及有別於缺乏彩虹色的白色邊緣的剩餘 Malagasy 同類到, 或較深色的靠近邊緣的帶,之上垂直的鰭.(參考文獻 57724)

Found in a wide range of habits: stream flowing under relatively intact forest cover at an altitude of 70 m above sea level consisting of a series of quiet pools with clay/sand bottoms, interspersed with short stretches of flowing water over sand/ gravel bottoms and with very turbid water; and stream flowing through modified low-altitude rain forest at an altitude of 30 m above sea level consisting of clay/sand bottom, interspersed with patches of bedrock with clear water and moderate current (Ref. 57724). Feeds on terrestrial and aquatic insects (Ref. 57724).
