The Emperor Tetra originates from streams and rivers
in Colombia. The lower half of the body is black/blue while the top half
is creamy silver. The fins can have a yellow appearance. Emperors
like a dark, well-planted aquariums and caves. They also like open swimming
space. They don't school as readily as other tetras, but will do so if
there are 6 or more. They can undergo color changes, especially during
breeding. They eat flake foods, freeze dried bloodworms and brine
The female is lighter and the male has an extension of the black body line
into the tail fin, which results in three points to it. Emperors will scatter their
adhesive eggs in heavily planted soft water.
Live foods, water changes and termperature changes may help bring about spawning.
Spawning can take several hours. Eggs are scattered among fine
leaved plants and the parents should be removed before the fry hatch.
