Despite the similarity in name and shape, Paracyprichromis nigripinnis is quite different from the more common Cyprichromis. Paracyprichromis are not open water swimmers like Cyprichromis. Instead, Paracyprichromis prefer to stay close rock walls and along rocky bottoms. Both males and females display the neon blue striping, although the male's tends to be more prominent. They are best kept in groups with fish that aren't too aggressive and make great additions to Tanganyikan community tanks.
If you think you might want to keep a group of Paracyprichromis nigripinnis, head over to the Lake Tanganyika forum for advice on good tank mates and group sizes.
