What to know before you buy.
From Lake Tanganyika, the Tropheus Duboisi undergoes a remarkable color change: juveniles are black with white spots, while adults are dark blue/black with a vertical yellow or white band. They are highly aggressive towards their own kind and must be kept in large groups in very large tanks to manage their social dynamics.
