Duboisi Cichlid by LiveAquaria
The Tropheus Duboisi Cichlid originates from the rocky coastal waters of Northern Lake Tanganyika, Africa. As juveniles, they are completely black with many white spots. As they mature, the spots fade and their heads develop a blue coloration. A distinct wide yellow band appears just behind the pectoral fins.
Like other Tropheus species, Duboisi cichlids are highly aggressive toward their own kind and require a group of at least six individuals. They thrive best in species-specific aquariums or with other smaller, semi-aggressive Tanganyikan or Malawian cichlids.

I kept a group of six Duboisi cichlids in a 75-gallon tank with plenty of rocks. After a few weeks, the fish started showing their blue heads and yellow bands. They’re very active and territorial, so I had to ensure the tank had enough hiding spots. The aggression is intense, but with proper group size, they coexist well.

The fish look stunning when they mature. I started with juveniles and watched the color change over several months. They need a large tank and a lot of space, but once settled, they’re quite peaceful with compatible species.

I tried keeping them alone, which didn’t work. They became extremely aggressive and damaged the tank decorations. After adding five more of the same species, the behavior improved significantly. Now they share the space better.
