簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 13 - 15; 背的軟條 (總數) : 9 - 12; 臀棘: 3; 臀鰭軟條: 7 - 9; 脊椎骨: 25 - 27. Diagnosis: 14-18 gill rakers on first gill arch; no large spots on flanks (Ref. 81260). 4-6 bands or 2 rows of dark blotches and short horizontal lines usually visible when stressed (Ref. 50577, 81260). Relatively robust (body depth 26.7-38.2%, mean 34.4% SL); lachrymal depth less than 21% HL (Ref. 81260). No iridescence on cheek, operculum and flanks (Ref. 50577).
齒骨孔 5; 下頜有 2-3 列的單犬齒; 吻相當尖銳的; 沒有在頰，鰓蓋與側面上的彩虹色; 而且受驚的個體有兩列深色的縱向斑紋與小的斑塊.(參考文獻 50577) 尾鰭圓的。 (參考文獻 50577)
Prefers smaller rivers and creeks; normally found near the banks where plenty of hiding spots are available; diet consists primarily of small particles, preferably plant matter, although shrimp eggs and insect larvae are also taken (Ref. 52307). Monogamous (Ref. 52307), pair-bonding, ovophilic, biparental mouthbrooding species (Ref. 52307, 81260).
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
In aquaria, a monogamous, pair-bonding, biparental ovophilic mouth brooder. Eggs are deposited on hard substrate or on leaves and incubated by the female for the first 2 or 3 days; afterwhich incubation may be done by both male and female (but mainly by female) (Ref. 50577).非洲: 加彭。
