The Buenos Aires Tetra is a South American fish that will make a great addition to any community aquarium. It has a slender silver body with red fins.

The Buenos Aires Tetra can be housed in an aquarium with other soft water fish. Tetras are a schooling fish that work well in groups of six or more fish of the same species. Artificial plants, rocks and driftwood help to enhance its natural habitat and provide hiding spaces. The Buenos Aires Tetra will eat most live plants, except Java Fern.

Buenos Aires Tetras breed occasionally in an aquarium setting and a hospital or "breeding tank" will be necessary. Slightly acidic water is best for optimal breeding habits. After the eggs begin to hatch, removing the parents will reduce the number of lost fry.

The Buenos Aires Tetra will accept many small foods such as brine shrimp or daphnia, freeze-dried bloodworms and tubifex, and a high quality flake food.

Approximate Purchase Size: 1/2" to 1-1/4"

Great, full bodied, and active fish. The Buenos Aires Tetra is a fantastic species to watch. These fish are rather aggressive eaters, be aware of this if you have shy or finicky eaters in your community tank. As noted in the description, they will eat most of your plants, I have a mature java fern that they generally leave alone.

the buenos aires tetras are awesome i will say they didn't get along great for the first couple of hours with my other tetras, they where chasing them around and nipping at their tails but they seem to have settled down they are pretty fast and steal food form the other fish but other than that they are awesome

VERY active tetras. Does best as a school in a long tank. I have a school of 7 that i use as dither fish with my Silver dollars to calm them down.
