The Flag Tetra was
introduced to the aquarium in about 1910, and it is not as
hardy as many of the more popular tetras.
The general shape of the body of the Flag Tetra is similar
to the Black Neon Tetra. As with other tetras, the Flag
Tetra male is different from the female in that it is slimmer,
whilst the female is bulkier and more rounded.
The Flag Tetra has a reddish-brown back, and the abdomen is
silvery, sometimes with an olive-green tinge. It also has
a band of colour along its body, which is a black stripe, with
a strip of green/yellow above it, and an orange line above
that.
As with other tetras, Flag Tetras like to shoal together, so
it is best to keep between five and eight together at a
time.
Flag Tetras will breed in captivity, spawning will generally
take place out in the open water, and the eggs will drop on to
the bottom, or rest on a leaf. The parent fish should be
removed immediately, as Flag Tetra will eat their own eggs or
young.
Flag Tetra do not breed very successfully, as the eggs are
susceptible to fungus, and the young often get diseases.
