Fancy an archerfish you can keep in freshwater?
Toxotes blythii is a rare and beautiful freshwater archer from Burma.
Scientific name: Toxotes blythii
Common name: Clouded archerfish
Origin: Burma
Size: Unknown for sure; likely around 15cm/6in
Diet:
Wild archerfish feed mainly on insects, spiders, crustaceans and small
fish. In captivity they greedily take all sorts of dried and frozen
foods including good quality floating pellets.
Water:
Other freshwater archers do well in moderately soft to hard water
conditions, and Toxotes blythii is probably similar. Does not need to be
kept in brackish water. Temperature 25-28°C/77-82°F, pH 6.5-8.0.
Notes: Toxotes blythii comes from a very restricted
part of Burma that isn’t easy to get.
The other archerfish are gregarious in the wild,
particularly when young, but become more territorial as they mature, and
Toxotes blythii is presumably no different. Under aquarium conditions
they are probably best kept in groups of three or more specimens that
allows any aggression between individuals to be diffused throughout the
group without any serious harm. In pairs it often happens that the
dominant specimen bullies the smaller one to death. Singletons can be
maintained successfully, but archers kept this way are sometimes a bit
shy and nervous, though much will depend on their tankmates.
Keep
away from boisterous, nippy or aggressive tankmates, as well as
anything small enough to swallow (archers can eat prey up to about half
their size).
Like
other freshwater archers, Toxotes blythii probably tolerates salt well,
which can be useful to know when treating for whitespot and velvet.
Aquarium:
Archerfish are riverine fish that appreciate swimming space and a
strong water current. A singleton might be maintained in a 50 gal.
aquarium with a decent filter. Provide plenty of shade at the surface,
either by using floating plants or normal plants with leaves that float
up to the surface. All archers will jump out of uncovered tanks.
Sexing:
Archerfish are not sexually dimorphic. Indeed, their breeding biology
is a complete mystery! The brackish water species are said to swim to
coral reefs and spawn there, but that presumably isn’t the case with
freshwater species like Toxotes blythii.
