Cichlidae

Protomelas similis
FISH SPECIES
Cichlids belong to the family Cichlidae and are especially diverse in Africa and the Americas. The family includes small, colorful specialists as well as larger food and game fish.
01 / NATURAL HISTORY
A single nostril on each side of the head and specialized throat jaws help characterize the family. Cichlids are also known for varied feeding strategies and unusually diverse parental care.
02 / LIFESTYLE
Cichlid life histories are renowned for intricate social hierarchies, territorial zoning and exceptional parental investments. Breeding adults carefully clean substrates for spawning, vigorously ward off egg predators, and in mouthbrooding lineages, protect developing embryos inside the buccal cavity for weeks. Complex body posturing, fin flares and color transformations establish dominance without lethal physical conflict.

04 / FIELD NOTES
In mouthbrooding species, a parent gathers fertilized eggs into their buccal cavity, gently churning and oxygenating them for weeks until fry develop and can swim independently.
Africa's Great Rift Valley lakes (Victoria, Tanganyika, and Malawi) and the freshwater basins of Central and South America support thousands of ecologically diverse cichlid species.
Most cichlids possess strong territorial instincts rooted in defending substrate spawning sites and food boundaries, reacting vigorously to perceived visual rivals.
