Electric Yellow Cichlid
Labidochromis caeruleus
Type: freshwater, benthopelagic

Physical Characteristics
An elongated, laterally compressed body with a vibrant electric yellow coloration. It features a prominent black horizontal stripe along the dorsal fin, which is more pronounced in males. The anal and pelvic fins also contain black margins.
Habitat & Distribution
Endemic to Lake Malawi in Africa, specifically found in the rocky shoreline areas (mbuna habitats) along the central western coast. It prefers deep water up to 40 meters.
Size & Weight
Typically reaches 7.5 to 10 centimeters (3-4 inches) in length, though some individuals in optimal conditions may reach 15 centimeters.
Similar Looking Species
May be confused with other yellow mbuna cichlids like Metriaclima lombardoi (Juveniles/Females), but the distinct black-edged dorsal fin is a primary identifier for Labidochromis caeruleus.
Ecological Role
Acts as a secondary consumer within the rocky lake ecosystem, feeding on invertebrates and controlling small organism populations.
Diet
Omnivorous; it feeds primarily on lithophilous (rock-dwelling) invertebrates, small crustaceans, and insects, while occasionally grazing on algae/periphyton.
Behavior
Unlike many mbuna, it is relatively peaceful. It remains mostly solitary or in small groups and is diurnal, being active during the day among rocky crevices.
Reproduction
Maternal mouthbrooder; the female carries fertilized eggs and fry in her mouth for approximately 3 weeks for protection until they are free-swimming.
Conservation Status
Least Concern (IUCN), though localized populations may face pressure from the aquarium trade and habitat degradation.
Identification Tips
Look for the bright yellow body paired with a bold black band running through the length of the dorsal fin. Pectoral fins are usually transparent.
Interesting Facts
In the wild, there are actually white and blue variants of this species; the electric yellow morph became the most famous due to its popularity in the aquarium hobby.
