Facultative air-breathing (Ref. 126274); Occurs upstream. Prefers to live in small, moderately sunny and shallow creeks with sandy to sandy-muddy bottoms. Also occurs on the edges of stagnant zones of flooded forests (dams, lakes). Populations living on darker substrates have more and larger spots. Sexual dimorphism is well marked, the pectoral fins in the male are markedly longer and thicker due to the presence of a number of spikelets (Ref. 35381).
向上游生存。 偏爱生活于小的, 一般晴朗与水浅的小溪具有沙的对沙泥底。 也生存于被水淹没的森林污浊区域的边缘。 (水坝, 湖) 生活在较黑的底部上的族群有更多与更大的斑点。 性的同种二形是显着, 在雄鱼的胸鳍显着地更长与更厚由于那有一些小穗状花小穗.(参考文献 35381)
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
The female holds 2-4 eggs between her pelvic fins, where the male fertilizes them for about 30 seconds. Only then the female swims to a suitable spot, where she attaches the very sticky eggs. The pair repeats this process until about 100 eggs have been fertilized and attached (Ref. 1672).南美洲: 在法屬圭亞那的蘇利南與 Iracoubo 河流域的蘇利南河流域。
