Electric yellow cichlid overview
The electric yellow cichlid (Labidochromis caeruleus), often called the yellow lab, is a mbuna from Lake Malawi. Its bright yellow body makes it one of the most recognizable African cichlids in the trade. It stays relatively small, commonly cited at around 4 inches, and is considered one of the milder mbuna. For more on the group, see our mbuna cichlid care guide.
Are they hard to keep?
Electric yellows are generally regarded as hardy and are often recommended to beginners moving into African cichlids. They still need the right setup: hard, alkaline water, strong filtration, rockwork, and sensible stocking. Most problems come from overcrowding, poor water quality, or being kept with fish that bully them rather than from fragile health. Even though they are milder than many mbuna, they can still be territorial, especially males.
Tank size and setup
A tank of around 30 to 55 gallons is a common range, with larger tanks easier to manage if you want a group or several species. Provide rock caves and sight breaks, and use sand or fine gravel. Secure rockwork on the bottom of the tank so burrowing does not cause collapses.
Water and feeding
Typical guidance is hard, alkaline water with temperatures in the mid-70s to low 80s Fahrenheit and pH around 7.8 to 8.6. Perform regular partial water changes.
In the wild they eat a mix of small invertebrates and algae-associated growth, so they are more omnivorous than some mbuna. A good-quality cichlid pellet or flake with some vegetable content works well. Keep high-protein foods modest to reduce the risk of digestive trouble.
Good tank mates
The safest companions are other peaceful or moderately aggressive Lake Malawi mbuna of similar size. Avoid keeping them with large, aggressive cichlids that may bully them, and avoid fish that need soft or acidic water. Do not keep them with another yellow fish, since males may fight look-alikes. See our African cichlid care guide for broader stocking advice, and compare with red zebra care if you are planning a mixed group.
Male or female?
Sexing can be tricky. Males commonly show a more intense yellow and a black stripe on the dorsal fin and a more defined black stripe along the pelvic and anal fins, while females tend to be paler with less marked fins. Differences can be subtle in young fish and between individuals, so treat these as general indicators. Buying a group and observing behavior as they mature is common practice.
Why did my yellow cichlid turn dark?
Color changes can have several causes. Stress from aggression, a new tank, or sudden changes in water conditions may dull or darken a fish. Dominant fish can also darken when displaying. Dark patches or poor color may signal poor water quality or illness. Test your water and watch for other symptoms; our guide to stress spots on fish explains how stress shows up in color. Note that some mbuna may naturally develop darker coloring when they are mature or when breeding. If the darkening persists and the fish seems unwell, check conditions and consult an experienced aquarist or vet.
Breeding
Electric yellows are maternal mouthbrooders. The female picks up the eggs after spawning and carries them for a few weeks. Provide hiding places, avoid overcrowding, and consider moving a stressed female to a quiet tank. The fry are relatively easy to raise on finely crushed flakes or small foods, but plan ahead for the number of fish.
