Remark: This has been a popular aquarium fish for over 50 years but was just given a name in 1997.  <i>P. zigzag</i> is a relatively small species with a broad, almost black zigzag band across the body.  Small specimens can be confused with <i>Copella nigrofasciata</i> but in <i>C. nigrofasciata</i> the black band is straight and there is a row of red spots along its dorsal border.
