Distribution: The Red-eyed Tetra or Yellow-banded Moenkhausia was described by Steindachner in 1907. They are found in South America, in Paraguay, eastern Bolivia, eastern Peru, and western Brazil. Aquarium fish for the hobby are now bred extensively in Asia.
Status: The species is not listed on the IUCN Red List.
The Red Eye Tetra is a great little tetra
that needs to be kept in a school of 5 or more. They make ideal members of a
planted, peaceful community tank and should bring a decent amount of activity
to your aquarium. The top of the eye socket is red, hence the name. The first
half of the caudal fin (tail fin) is black and the main part of the body is
silver.
The Red Eye Tetra is very peaceful if kept
in groups, but may get a little fin nippy if kept as a single. Other tetras may
pick on them at times, so keep an eye on them. They do make a great freshwater
aquarium beginner fish because they can be relatively hardy and their peaceful
nature.

Water Region: Top, Middle, Bottom:
These fish will swim in all areas of the aquarium. Social Behaviors: The Red-eyed Tetra or Yellow-banded Moenkhausia are generally a good community fish.
Habitat/Care:
Red Eyes tolerate a range of water
conditions, from hard alkaline to soft acidic water. They prefer a dark
substrate and plant cover along the sides and back of the aquarium. It is
advisable to keep them in schools of six or more.
Diet:
Like most tetras, Red Eyes will accept
virtually any foods. A varied diet of flake foods coupled with occasional
feedings of live or frozen foods, will keep them in top condition.
Water
Conditions
The preferred temperature range of this
species is 23 - 28 degrees C (73 - 82 degrees F) although they will survive a
little outside this. I would note that their natural range actually goes
outside the tropics, so there might be some populations that are more cold
resistant, but I have never tried the Red Eye Tetra in an unheated tank, and I
do not recommend this.
In the wild they mainly come from soft,
slightly acid water, but they can adapt even to hard alkaline water, so they
are happy in a normal community aquarium of mixed fish with a temperature of 24
degrees C (75 degrees F), neutral acidity and some hardness.
Sexual Differences:
The only truly distinquishing feature to differentiate the sexes
is that a mature female has a more rounded stomach
To breed the Red Eye Tetra it is necessary
to have very soft, slightly acidic water with floating plants. They will lay
their eggs among the roots of the floating plants, although many of the eggs
may still end up on the bottom of the tank. The parents will eat their eggs and
babies, so they are normally removed after spawning.
Females are larger and have a more rounded
abdomen than the males. When attempting to breed them, a separate breeding tank
should be set up with slightly acidic, very soft water (4 dGH or below). If
floating plants are provided, as the breeding pair will often lay eggs among
the plants.
The eggs should hatch in about one or two
days, and the fry should be free swimming a few days later. The baby Red Eye
Tetras are slightly bigger than the babies of most tetras and they are vigorous
and not as hard to raise as some egg laying fish babies are.
Once spawning has occurred, the mating pair
should be removed, as they will consume the eggs and hatching fry. One to two
days after they are laid, the eggs will hatch. The fry can initially be fed
commercially prepared fry foods, then freshly hatched brine shrimp, and
eventually finely crushed flake foods.
