General: The acei cichlid was first discovered in 1922 by Charles Regan. Generally, it is found in northwestern Lake Malwai, although there are currently four confirmed geographical variants. Aceis do well in an aquarium that is aquascaped with sand, rock structures, caves, and large open swimming areas. They are rather social and peaceful when it comes to cichlids.

Fecundity: Acei cichlids typically will spawn if there is a small group of fish consisting of one male to a few females. They will typically spawn on horizontal surfaces such as slate, where the female and male will swim circling each other; laying, fertilizing, and picking up the eggs in the process. Around 20-50 fry are produced per spawn.

Water Chemistry: Acei cichlids prefer a water temperature that ranges from 76-82F, a KH that ranges from 10-15, and a pH that ranges from 7.8-8.6.

Aquarium Diet: Acei cichlids are herbivores, and prefer fish flakes specially prepared for herbivorous fish and algae wafers. Aceis will also tend to graze on algae in the aquarium and plant material if there is any. Occasionally they can be given frozen foods such as brine shrimp to encourage spawning.

Dimorphism: Male and female acei cichlids look very similar, although males generally will grow around one to two inches larger than females. Also, males tend to have more egg spots and at times will flare their fins to show off for females in the aquarium.

Compatability: Acei cichlids, as stated earlier, are more peaceful and social when it comes to cichlids. If placed in an aquarium with more agressive species, they can get bullied. A good tank mate for the acei would be the electric yellow cichlid (Labidochromis caeruleus), which has a similar temperament. Acei cichlids generally feel most comfortable when in a school of at least five other aceis.
