Duck Head Knifefish (Parapteronotus hasemani)

$69.99

A little known and rarely imported knifefish found in parts of the middle and Western Amazon and its tributaries, the Duck Head or Duckbill Knifefish is a medium, heavy-bodied species that displays strong sexual dimorphism. Adult males have an elongated snout with large jaws that give the species its common name while females retain a more typical knifefish head shape. This species is more territorial than some other knifefish, and males especially will fight if kept together in anything but the largest aquariums. Relatively hardy, they are not overly particular about water conditions and will readily accept most frozen foods.
