The Buenos Aires Tetra is a nice looking and very hardy fish that can live well in almost any type of water. It also grows a little larger than other Tetras, reaching about 10 cm. It's peaceful and very easy to keep in community tanks, but beware: the Buenos Aires Tetra is an avid plant eater, so you must keep it with plenty of fast growing plants, or no plants at all. The fish portrayed above is a male, females have a much more rounded body. Breeding is said to be relatively easy. The Albino variety is also available for the hobby.
I have three of these tetras that are about 3-4 inches long. They eat a lot of food when when I feed them. The also like to fight with my bala sharks. They love the brine shrimp that I feed them.
These fish need a long tank. I had three in a little 40 liter aquarium for a while, and they spent all their time attacking each other or hiding out in separate corners. I finally moved them to a 80 L long, and now they school quite happily and aren't anywhere near as aggressive as they used to be (the little one still always has a nipped fin or two). These fish are extremely hardy and are voracious feeders -- it's actually somewhat difficult to overfeed them. For both these reasons, they make excellent beginner fish.
I have like 10 Buenos Aires Tetras and they are very active in the tank. They also play with others. The females are bigger while the males a little smaller and slender. This is a good fish to have.
I have an Albino Buenos Aires Tetra that is about 4 cm long. It was a great addition to my to my 95 L tank. There are 12 other fish and it rarely bothers anyone. I have plastic plants with a stand rock and drift wood. A very active swimmer and aggressive at feeding time. Love to have it.
These fish make great dither fish if you've got shy South American fish like Oscars, Pacus, or Jack Dempseys. They're fast, and so long as the fish you're trying to "dither" out aren't much bigger than they are, you don't have to worry about them being lunch either. They get really, really red if they have enough access to fresh algae in your tank.
