The Buenos Aires Tetras are active and beautiful. I kept them in a 20-gallon tank with driftwood and plants. They swim together in groups and add a lot of movement. The red fins stand out well against the silver body. I’ve had them for three months and they’re still healthy and active.

Great addition to my community tank. I kept six of them with other soft water fish. They don’t stress the others and enjoy the plants. The only thing is they eat some of the live plants, so I removed Java Fern to protect it.

I tried breeding them once and it worked well. I used a separate tank with slightly acidic water. After the eggs hatched, I removed the parents and the fry survived. The fish are easy to care for and look very natural in the tank.
