Comments: Occurs in backwaters or streams with little or no current and with substrate generally comprising of a mixture of sand and mud, frequently with abundant flocculent sediments and leaf litter (Ref. 79584).  Forms large schools (Ref. 79584). The extremely long intestinal tract, high gill-raker counts and the habitat preference of this species indicate a detritivorous diet (Ref. 79584).
