I purchased four Melanochromis cyaneorhabdos, previously known as Maingano, and housed them with my Chindongo saulosi. They are incredibly striking fish; both males and females display vibrant blue bodies with distinct horizontal stripes, with colors being especially vivid on the dominant male.
Behavior and Aggression
M. cyaneorhabdos is a real bully. Generally, the species is very aggressive, and a dominant male can quickly seize control of the entire tank. Based on my experience, it is best to avoid mixing them with peaceful species. Instead, they should be kept with other hardy mbunas; overstocking is often recommended to make it difficult for individuals to establish dominant territories.
Breeding Challenges
As maternal mouthbrooders, they breed readily, but the process can be dangerous for the females due to high aggression levels. I unfortunately lost one female who was killed while carrying eggs because I delayed moving her to a separate tank.
In a subsequent attempt, I managed to save 16 fry, but reintroducing the female to the main tank proved nearly impossible, as the other fish immediately attacked her.
Appearance and Sexing
Sexual dimorphism is very minor in cyaneorhabdos. Unlike many other mbunas where sexes have different colors, both Maingano males and females share the striped pattern. I could only distinguish them with certainty after the females had carried eggs. The fry resemble miniature versions of the adults almost from the start.
