大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 27.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 125980); 最大體重: 290.00 g (Ref. 125980)
背棘 (總數) : 0; 背的軟條 (總數) : 11 - 12; 臀棘: 0; 臀鰭軟條: 9 - 10; 脊椎骨: 31 - 33. Differs from other Cyphocharax (except aspilos) by the absence of multiple series of longitudinal patterns of dark pigmentation on body, the absence of a large spot of pigmentation on the body, the absence of a large spot of pigmentation on the dorsal fin, the absence of a rotund spot or longitudinal stripe of dark pigmentation on the midlateral surface of the caudal peduncle, the number of lateral line scales, and the depth of caudal peduncle of 0.13-0.15 of SL (Ref. 11334).
有別於其他 Cyphocharax(除了 aspilos 以外) 在身體上的深色顏色的藉由缺少多個成列縱向圖案, 那在身體上缺乏一個顏色的大斑點, 那在背鰭上缺乏一個顏色的大斑點, 那在尾梗的側面中央表面，側線鱗片的數字上缺乏一個圓的斑點或深色顏色的縱向斑紋, 與尾柄的深度 0.13-0.15 SL.(參考文獻 11334)
Inhabits rivers or creeks of moderate current between 20 and 10 m elevation. Abundant in shallow waters over sand or mud bottoms where it feeds on detritus, diatoms and algae (Ref. 36880). Found in swamps or marshes and rivers (Ref. 26543). Feeds exclusively on detritus (Ref. 26543).
棲息於在 20 與 10 公尺海拔之間的平穩水流的河或小溪。 豐富的在淺水區中之上沙或泥底部在那裡它吃碎屑，矽藻與藻類.(參考文獻 36880) 發現於沼澤或濕地與河了。 (參考文獻 26543) 只吃碎屑。 (參考文獻 26543)
