Peaceful but may scare shy species with its active swimming and large adult size. Recommended for most community tanks however. Ideal tankmates include other tetras, rainbowfish, Corydoras, Loricariids, Synodontis and various peaceful cichlids such as Pelvicachromis sp. or Cleithracara. Do not keep congo tetras with fin-nipping species as the spectacular fins of the males will be destroyed. Similarly they should not be kept with boisterous tankmates due to their shy nature. P. interruptus should be kept in a mixed-sex shoal for the best effect.
