Pseudotropheus acei is a species of cichlid endemic to Lake Malawi in East Africa. It is a member of the Mbuna group, which are rock-dwelling cichlids. Unlike many other Mbuna, P. acei is often found in open water near submerged logs and branches, rather than strictly rocky environments. They are known for their distinctive coloration and relatively peaceful temperament compared to other Mbuna.
Physical Characteristics
- Body shape
- elongated
- Coloration
- The body is typically a vibrant blue to purplish-blue, often appearing iridescent under certain lighting. The most distinguishing feature is the bright yellow caudal fin (tail fin) and often yellow pectoral and pelvic fins. Some regional variants, such as the 'Msuli' or 'Ngara' Acei, may exhibit white or cream-colored fins instead of yellow.
- Scale type
- ctenoid
- Mouth position
- terminal
- Distinctive features
- Vibrant blue body coloration, Bright yellow caudal fin (tail fin), Often yellow pectoral and pelvic fins, Relatively slender body compared to other Mbuna
- Dorsal fin
- Long, continuous dorsal fin with spiny rays anteriorly and soft rays posteriorly, typically matching body color.
- Tail fin
- Large, fan-shaped caudal fin, typically bright yellow (or white/cream in some variants).
- Pectoral fin
- Paired pectoral fins, often yellow (or white/cream).
- Distinctive fins
- The contrasting yellow (or white) fins against the blue body are the primary distinguishing feature.
Identification Tips
Body Color
Look for a distinct blue to purplish-blue body.
Fin Color
The most reliable identifier is the bright yellow caudal fin. Pectoral and pelvic fins are also often yellow. Note that some variants have white fins.
Habitat Preference (in wild)
While an Mbuna, they are often found near submerged wood rather than exclusively rocky areas, which is unusual for the group.
Habitat
- Water type
- freshwater
- Depth
- Typically found in shallow to moderate depths, often between 5-20 meters (16-65 feet).
- Environment
- Unlike many Mbuna, P. acei is often found in areas with submerged logs, branches, and root systems, as well as rocky outcrops. They are known to graze on algae growing on these surfaces.
- Geographic range
- Endemic to Lake Malawi, East Africa. Specific populations are found along the western and northern shores of the lake, including locations like Ngara, Msuli, and Itungi.

- Compatibility: Best kept with other Mbuna cichlids of similar size and temperament. Avoid keeping with overly aggressive or very docile species. A single male with multiple females is ideal to disperse aggression.
- Special requirements: Requires a tank with plenty of open swimming space, as well as hiding spots among rocks and driftwood. A sandy substrate is preferred. Good filtration and regular water changes are essential to maintain water quality.

Key Facts
Unique Habitatbehavior
Unlike most Mbuna cichlids that are strictly rock-dwellers, Pseudotropheus acei is often found foraging around submerged logs and branches in Lake Malawi.
Algae Grazerbehavior
Their diet primarily consists of algae scraped from rocks and wood, making them important herbivores in their ecosystem.
Mouthbrooderbehavior
Like many Lake Malawi cichlids, P. acei is a maternal mouthbrooder, where the female carries the eggs and fry in her mouth for protection.
Color Variantsinteresting
While the 'Yellow-tail' is most common, there are also 'White-tail' or 'Msuli' variants of P. acei, which have white or cream-colored fins instead of yellow.
Safety Information
Safe- Safety level: safe
- Venomous: No
- Edibility: not recommended
- Handling notes: No specific handling precautions beyond standard fish handling to minimize stress. They do not possess venomous spines.
