Congo tetras are one of my favorite fish for a non-aggressive community tank. Their good nature and affinity for slightly acidic water makes them a great fit for a tank with angels and/or discus. They are active in the tank and will swim in the open water but they don't really bother other fish. They can also be kept with smaller tetras and other smaller community fish with no issues.
Congo tetras eat buts and larvae in the wild. In the fish tank, they will eat flakes but should be given live or frozen brine shrimp and blood worms on occasion or they can lose their color. They should be kept in at least a 30 gallon tank and work great in groups. A school of Congo tetras is pretty amazing to watch. Their iridescent bodies are so pretty and they look really elegant in the tank.
