I bought a group of six Buenos Aires Tetras for my 30-gallon community tank. They’ve been active and colorful since day one. The red fin highlights stand out well in the light. They swim together in a coordinated way, which adds a lot of visual interest. Easy to maintain and don’t stress other fish in the tank.

The fish arrived healthy and were active right away. I kept them in a group of seven with other community fish. They don’t fight or hide, and they swim freely. The silver body with greenish-gold sheen is quite noticeable. I’d recommend them to anyone starting a freshwater aquarium.

Great addition to my tank. The movement they create is lively and engaging. I’ve had them for three months now and they’ve stayed healthy. They adapt well to the water parameters and don’t require much attention. Perfect for a beginner-friendly setup.
