Yellow Tailed Acei (Pseudotropheus acei )

Bold, active, and strikingly coloured — the Yellow-Tailed Acei (Pseudotropheus acei) is a popular and attractive Lake Malawi Mbuna cichlid, prized for its distinctive deep blue-purple body and vivid yellow to orange-yellow tail fin. Hardy, active, and relatively peaceful for an Mbuna, the Yellow-Tailed Acei is an excellent choice for Lake Malawi community aquariums.

Overview

Appearance

The Yellow-Tailed Acei displays a deep blue to blue-purple body with a vivid yellow to orange-yellow caudal fin — the bold colour contrast that makes this species immediately recognizable and highly attractive. Both males and females display similar colouration, though males are typically more intensely coloured. The vivid yellow tail against the deep blue body creates a striking, graphic colour combination that stands out in any Malawi aquarium.
