The species was reported to swim near the bottom to feed, substrate containing food are scooped and ingested. Stomach content with diatoms, desmids, and epiphytic filamentous algae. Apparently territorial, guarding areas with submerged grassy plants with algal cover, defending with chases, nips, strikes, and mouth fighting. May form schools of up to 30 individuals. Also reported to occur in small streams or places of weak currents in adjoining swampy areas. Captured along banks of rivers (Ref. 11334).
此鱼种被报告在底部的附近游泳觅食, 包含食物的底部被铲取而且摄取。 胃内容物有硅藻,鼓藻与附生植物的菌丝藻。 显然具有领域性, 和水下的长满草的植物用藻类覆盖,以追逐防护, 保卫区域捏,攻击, 与嘴战斗。 可能形成鱼群向上到 30个个体。 也报告在邻接沼泽的区域中出现在小的溪流或水流弱的地方。 沿着河的岸捕获。 (参考文献 11334)
