Tropheus annectens

Tropheus annectens is a vibrant, herbivorous cichlid from Lake Tanganyika, known for its bright colors (like yellow barring and blue eyes) and territorial rock-dwelling habits, requiring hard, alkaline water, plenty of rocks for grazing/hiding, and a spirulina-rich diet, with a unique feature being its four anal fin spines, differentiating it from other Tropheus species.
