Giant Silver Hatchet (Thoracocharax securis)


A rarely seen relative of the common silver hatchet (T. stellatus), the Giant Silver Hatchet is found throughout Central and Western Amazon tributaries. In the aquarium, they are hardy and peaceful schooling fish like most hatchets. This species is shy by nature and fast moving, large, or aggressive tankmates should be avoided. Their tank should be kept tightly covered as they are easily spooked and likely to jump out if given the opportunity. As a surface feeder, they primarily eat  insects in the wild but will accept flake and other floating foods like freeze dried bloodworms in the aquarium.
