Way of life
Paracyprichromis nigripinnis lives in large flocks of several hundred individual animals, relatively true to their location, at depths of more than 20 meters in front of vertically sloping cliffs. The fish feed primarily on zooplankton , especially copepods , and planktonic algae. They are mouthbrooders and the reproductive, 8 to 10 cm long females keep the large, yolk-rich eggs, larvae and juvenile fish in their mouths until the latter swim freely with a length of up to 1.8 cm. More than 4 weeks pass between egg laying and free swimming. After swimming free, the young fish first live in caves and crevices in the rocks. As they get bigger, they gradually leave their hiding places to join the schools of adult fish.
