The Archerfish is a moderately elongated, laterally compressed
fish with a pointed head. The eyes of the fish are strikingly
large, and the deeply cleft mouth faces slightly downward.
The Archerfish
has a yellow-green or brownish back, and the flanks are pale grey
to silvery, and marked with four to six broad black transverse bars.
The first bar runs across the eye of the Archerfish, and the last
one is on the caudal peduncle.
There are no
obvious differences between the male and female Archerfish, and
they are not known to have bred in captivity.
Small Archerfish
tend to be sold as freshwater fish, but they do prefer brackish
water, and will thrive better in this as they increase in age, so
it is advisable to add one teaspoonful of sea salt for every gallon
(four litres) of water.
Archerfish are
best kept in an aquarium with rocks and shallow water, and with
plants that grow up above the surface.
Archerfish are
well known for their ability to shoot drops of water to dislodge
insects above the water surface. The tongue and roof of the
mouth of the Archerfish form a tube. When the mouth is filled
with water, the sudden closure of the gill covers forces the water
along the tube and out of the mouth.
A young Archerfish
learns how to shoot when it is only 1" (2.5cm) long, and the range
of the shot will vary depending on the size of the fish. An
old Archerfish which is fully grown can bring a fly down at a range
of five feet (1.5 meters).
Archerfish can
be aggressive towards each other, so it may be advisable to keep
one on its own, or with a fish of a different breed, but of a similar
size.
