The Silver Hatchetfish originates in still water from
Brazil to Argentina. The term silver hatchet refers to a number of
hatchetfish, including Thoracocharax
stellatus (the Spotfin Hatchet) and Gasteropelecus sternicla (the River Hatchet,
pictured above). They have
an extended lower body with a shape reminiscent of a pelican. This
extended area has large silver scales. The pectoral fins are very long and
the dorsal area is flat, which helps them skim the surface of the water.
The back is olive brown.
Silver Hatchets are one of the best jumpers in
the tropical fish world. In the wild they are able to catch flying
insects. You can hear them splashing in the water regularly. If the
tank is not covered, they will frequently jump out. You also need to
ensure they can't jump in to an external filter. They are schooling fish
and should be kept in groups. Tank mates should be peaceful and occupy the
lower levels of the aquarium. Silver Hatchets will eat flake foods, blood
worms and brine shrimp.
Females are larger than males. They have not been bred
successfully. Silver Hatchets aren't recommended for beginners.
