The most peaceful cichlid is the keyhole cichlid. These South American cichlids are shy and relatively friendly. When attacked, they prefer to run away rather than fight. Moreover, keyhole cichlids are also reclusive. They love spending most of their time hiding under plants and tank decorations.
Additionally, keyhole cichlids are relatively small, only growing to 5 inches (12 cm) in length. Due to their small size, they’re unlikely to attack and munch on their tankmates.
Aside from keyhole cichlids, here are some other relatively peaceful cichlids:
- Rainbow cichlids
- Severum cichlids
- Kribensis cichlids
- Angelfish
- Bolivian rams
- German blue rams
- Yellow lab cichlids
- Blue acaras
