簡短描述
檢索表 | 型態特徵 | 形態測量圖
Diagnosis: Juveniles have an uninterrupted dark band along middle of side, young and adults are uniquely distinguished among species of Cichla by the color pattern with lateral band transformed to row of irregular dark blotches and six or seven narrow dark vertical bars across side below dorsal fin (corresponding in position to bars 1, 1a, 2, 2a, 3, additional bar below end of soft dorsal in base, and occasionally one anteriorly on caudal peduncle). The adults with several small black blotches posterior to the orbit and on gill cover. All sizes with no light spots on the side (vs. present in most other species of Cichla). Lateral line almost always continuous; scales in E1 row 96-108 (Ref. 57716).
鑑別: 稚魚有一個不間斷的深色條紋沿著側邊的中央, 幼魚與成魚獨特地用被越過側邊在背鰭之下轉換到不規則黑色斑塊與六或七個狹窄的深色縱帶的列的側面的條紋在 Cichla 的種之中被顏色圖案區別.(符合位置到橫帶 1,1 一, 2,2 一, 3, 附加的橫帶在末端之下軟的背部在基底中, 與偶然地一前面在尾梗上) 那成魚有一些小的黑色斑塊在眼窩後面與在鰓蓋上。 所有的大小側邊上沒有淡色的斑點。 (vs. 出現在 Cichla 的其他大部分種) 側線幾乎總是連續的; 在 E1 列 96-108 的鱗片.(參考文獻 57716)
Often captured near submerged rocks or woody structure in the primary river channel within or near swift current. Diurnal piscivore. Feeds mainly on fish (Ref. 27531).
時常在初期的河峽道中的水下岩石或木本的結構附近捕獲在或裡面在湍急的水流附近。 日行性魚食性。 主要吃魚。 (參考文獻 27531)
