I kept a group of 8 Congo Tetras in a 60-liter tank. They swim together in a coordinated way and add a lot of visual interest. The water parameters were stable and I maintained regular water changes. They are active and peaceful, especially when kept in a group.

The fish are colorful and lively. I started with 6 fish and noticed they became more active after a week. I had to make sure the tank was not too crowded and that the water conditions were consistent.

Great addition to my community tank. They don’t disturb other fish and swim in tight schools. I keep them with peaceful species and avoid strong currents. Easy to care for once the setup is stable.
