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).
