          Pterophyllum leopoldi
        
        
          This is the third of the angelfish species currently generally
        
        
          accepted as valid.The other two are
        
        
          P.scalare
        
        
          and
        
        
          P.altum.
        
        
          However,
        
        
          since time immemorial the species
        
        
          P. leopoldi
        
        
          has been labeled P.
        
        
          dumerili in the hobby and in the trade; but
        
        
          P. dumerili
        
        
          is in fact a
        
        
          synonym of
        
        
          P.scalare.
        
        
          P. leopoldi
        
        
          comes from Brazil, where it is found together with
        
        
          P.
        
        
          scalare
        
        
          .
        
        
          P.leopoldi
        
        
          always swims in a typical "head-up" position,very
        
        
          reminiscent of the flag cichlids of the genus
        
        
          Mesonauta
        
        
          ,withwhich
        
        
          the angelfishes are closely related.The typical swimming position
        
        
          of
        
        
          P. leopoldi
        
        
          has even led to the lower caudal-fin filament always
        
        
          being longer than the upper.This character is so typical that it can
        
        
          be used to identify the species!
        
        
          P. leopoldi
        
        
          grows to around 15 cm long and its maintenance
        
        
          requirements are the same as those of the well-known
        
        
          P.scalare
        
        
          .
