Lethrinops – Msabi Sp. Rainbow

The Lethrinops genus includes several visually striking cichlids from Lake Malawi, and the Lethrinops Rainbow is among the most vibrant. Known for its iridescent colours and peaceful temperament compared to other Malawi cichlids, the Lethrinops Rainbow thrives in sandy-bottom environments and is ideal for experienced aquarists aiming to replicate biotope-accurate setups. Males display brilliant shades of blue, yellow, and red, especially during breeding periods, while females tend to be more muted in tone. Native to the deeper, sediment-rich zones of Lake Malawi, they are sand sifters by nature and require specific conditions to flourish.
