The fish, up close
The Johanni Cichlid, scientifically known as Pseudotropheus johannii, is a strikingly beautiful freshwater fish native to Lake Malawi in Africa. Known for its vibrant electric blue colouration with black vertical stripes, the Johanni Cichlid is a popular choice for aquarists seeking a colourful addition to their aquarium. These cichlids have elongated bodies and fins, with males displaying more intense colouration compared to females. They are relatively peaceful within their own species but can be territorial towards other fish, especially when breeding.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Johanni Cichlids are known for their semi-aggressive behaviour, especially during breeding periods. Males can be territorial and may display aggression towards other tank mates, so it is essential to provide adequate hiding spots and territories within the aquarium to minimise conflicts. They are active swimmers and will often sift through the substrate in search of food.
Tank planning
Maintaining water quality is crucial for the health of Johanni Cichlids. Regular water changes and monitoring of parameters such as pH, temperature, and ammonia levels are essential. Provide a well-decorated aquarium with rocks, caves, and plants to create a natural environment and establish territories. It is advisable to keep them in a species-only tank or with other Lake Malawi cichlids that can tolerate their semi-aggressive nature.
