One of the most easily kept fish, the Buenos Aires Tetra is great for the beginning aquarist!The Buenos Aires Tetras are very hardy, long lived, and prolific breeders. They are peaceful fish and will do very well in a community tank, but they do have a big appetite. They must be kept well fed because if they get hungry, they will nip the fins on any of their long-finned tankmates! For many years they were one of the most popular fish in the aquarium hobby. The Buenos Aires Tetra however, will eat live plants. With so many people today growing plants in their aquariums, they have fallen a bit out of favor. If you are keeping an aquarium with artificial plants they make a wonderful addition to a community tank. For more Information on keeping this fish see:

Distribution:
The Buenos Aires Tetra was described by Eigenmann and Ogle in 1907. They are found in South America
in the La Plata region,
Argentina, Paraguay and southeastern Brazil. They inhabit ponds and feed on worms, crustaceans, insects and plants.
Status:
The species is not listed on the IUCN Red List.
Description:
The Buenos Aires Tetra is a full-bodied large tetra species. It has a silvery color that picks up flashy neon highlights. The top and bottom of the tail fin is generally red, as are the pelvic and anal fins. The dorsal fin also
has a hint of red. Their most distinguishing characteristic is on the caudal
penduncle which has a bold black 'cross' shape.
Size - Weight:
These fish get up to 2.75 inches (7 cm).
Since they are omnivorous the Buenos Aires Tetra will generally eat all kinds of live. fresh, and flake foods. To keep a good balance give them a high quality flake food everyday. Feed brine shrimp (either live or frozen) or blood worms as a treat.
Water Region: Top, Middle, Bottom:
These fish will swim in all areas of the aquarium.
Acceptable Water Conditions:
This is a very undemanding species, as can be seen by the
wide range of acceptable conditions.
Hardness: 2-35° dGH
Ph: 5.8 to 8.5
Temp: 64-82° F (18-28° C)
Social Behaviors:
The Buenos Aires Tetra are generally a good community fish.
They are quite active and when provided with plenty of space they will school. As mentioned above they will eat most plants, with the probable exception
of Java Fern, and so should be kept with stone or plastic decorations.
And remember, keep them well fed so they don't snack on the fins of their
tankmates!
Sexual Differences:
The male will have brighter red fins, sometimes tending towards
yellow. The female is fuller bodied and has a more rounded stomach.
Breeding/Reproduction:
Suggested conditions: 75° F
The Buenos Aires Tetra are egglayers. The female will lay
eggs on plants or green floss.
See the description of how Characins breed
in Breeding
Freshwater Fish.

| I have three Buenos Aires tetras, and I just absolutely adore them! They all have such wonderful personalities. One is extremely shy and skitish, one is kind of the leader of the group, and the last just kinda follows the 'leader' around. They are so much fun to watch!!

| Got 5 of these guys in a smallish tank just for them, with a mopane bog wood root with a huge java fern stuck to it with a couple other plants up and a sump down full of more plants. The tank has a MILWAUKEE SMS122 pH/CO2 Controller so plants are always lush and the cylinders last forever because of the controllers... but back to these lovely fish... I looked in the tank one day last week and there, sitting pretty as can be is a 6th! A new baby the size of a small neon! I had no idea it had even been there obviously the dense java fern servered it well. Baby and 5 parents all doing great together.

| My Bruno Aries Tetra has such a personality! He is ina community tank with black neons and neon tetras, and schools well with them, and not agressive towards them at all. When I come up to the tank, he always swims over to whatever side I am on as if to say hi. 2004-08-23 |
