Caresheet: Electric yellow cichlid (Labidochromis caeruleus)

Looking to set up an aquarium to keep one or multiple of the endless colorful African cichlid species? Consider one of the classics of this branch of the aquarium hobby: the striking Labidochromis caeruleus, better known as the electric yellow cichlid.

Its small size and relatively peaceful nature make the electric yellow cichlid one of the best Lake Malawi cichlid species for beginners. Sound good? Keep reading for everything you need to know about this neon number!

Electric yellow cichlid (Labidochromis caeruleus) description

If you’re looking for an addition to your African cichlid tank that will really catch the eye, the electric yellow cichlid is exactly what you need. It lends its appropriate common name from the yellow color morph that naturally occurs in parts of Lake Malawi (other colorations in this species include white and blue with black stripes).

Electric yellow cichlids grow to a size of around 4”, making them one of the smaller African cichlid species. They’re notoriously difficult to sex as there is no overly sexual dimorphism, but males are generally slightly more intensely colored. Unlike the females, their pelvic and anal fins feature some black coloration.

Electric yellow cichlid (Labidochromis caeruleus) aquarium

Because these cichlids stay relatively small, an aquarium of 40 gallons (long) will suffice for a simple set-up. The tank should ideally be decorated in Lake Malawi style, with a light sandy substrate and plenty of rocks and caves. Plants are an option; some of the locations in the lake where electric yellow cichlids can be found are characterized by their dense fields of Vallisneria.

The water should be hard and basic with a pH around 8 and hardness level between 15 and 20 °H. Because the species is known to be relatively peaceful you’ve got some options when it comes to tankmates, mbuna or otherwise. Quick, sturdy schooling fish that don’t mind hard water, notably rainbowfish, are known to work well with electric yellows. They’re not biotope-correct, but definitely a beautiful addition with their stunning colors! When it comes to other cichlids, the best choices are species that are also relatively peaceful. Peacock cichlids, blue dolphin cichlids and zebra cichlids are among your possible options.

Keep in mind that the males of this species are known to display some territorial behavior, especially during spawning time. They will also chase females rather relentlessly, so be sure to keep your electric yellows in a harem that contains more females than males to disperse any aggression.

Caring for Electric yellow cichlid (Labidochromis caeruleus)

The electric yellow cichlid is a herbivore and its diet should reflect this. Although the fish will accept pretty much any food they can find, it’s a good idea to use a commercial food designed especially for herbivorous Rift lake cichlids as a staple. You can then supplement with plenty of other greens like fresh blanched vegetables and algae tabs, as well as the occasional serving of frozen or live food.

Interested in breeding your electric yellow cichlids? It’s not the easiest task, but it can be done. These fish are mouthbrooders, meaning the female will carry the eggs in her mouth until they hatch. As we’ve mentioned before the males of this species can be rather overly enthusiastic during breeding time, often pursuing potential mates until the point of exhaustion. If you’re looking to breed your electric yellows, be sure to keep plenty of females to each male to lessen stress. Include lots of caves in the aquarium decor and maybe consider going a size larger with the tank than you usually would in order to allow each cichlid to find a spot to retreat to if need be.


A Rift lake biotope filled with colorful species like the electric yellow cichlid is a spectacular sight to see. Unfortunately it does come with its particular challenges, especially in regard to choosing the right tankmates to avoid sparking World War 3 in your aquarium.
