布氏副爱丽鱼

Overview

The retiring Tanganyikan shoaling fish Paracyprichromis brieni depends on subdued light and suitable rocky retreats. Bright illumination or overly active companions can quickly suppress its coloration and confidence.

Distribution & habitat

It is widespread within Lake Tanganyika but associated with deeper water. Females use open space above rocky ground, while males occupy caves and overhangs, sometimes hanging upside down beneath them.

Aquarium setup

Provide swimming room alongside upright rock faces, substantial caves, and overhanging shelter. A taller aquarium allows open upper space above the rockwork. Keep lighting subdued rather than increasing brightness in an attempt to enhance the display.

Diet & feeding

Natural prey is zooplankton. Small mouths require appropriately fine food, and each individual must obtain enough. Most offerings are accepted, but live and frozen items should form the larger share.

Behaviour & compatibility

Keep at least eight in a loose social group. A dedicated aquarium best supports its quiet requirements. Any companions should be peaceful and avoid competing for the same water space. Boisterous rock dwellers and vigorous open-water rivals are unsuitable. Separate locality forms where breeding could mix them.

Sexual dimorphism

Males show brighter colors and longer extensions to the tail fin.

Breeding

Maternal mouthbrooding has been achieved in captivity, though infrequently. Maintain several females per male with numerous vertical walls and caves. A male establishes a sheltered territory and displays to passing females. During spawning, the female points downward near the foot of a rock wall while he remains above her. Eggs are released individually and gathered near the substrate during fertilization.

She holds the brood for roughly three to four weeks without feeding. Disturbance may cause premature release or loss, so moves require care. Parental attention ends when the young emerge; newly hatched Artemia nauplii are immediately suitable.

Notes

Eye size and the slender, elongated body help distinguish close lookalikes. Blue markings or a color-form sales name alone are not dependable identification.
