Tilapia (pronounced /tɨˌlɑːpiə/) is the common name for nearly a hundred species of cichlid fish from the tilapiine cichlid tribe. Tilapia inhabit a variety of fresh water habitats including shallow streams, ponds, rivers, lakes, and estuaries. Most tilapia are omnivorous with a preference for soft aquatic vegetation and detritus. Historically they have been of major importance in artisanal fishing in Africa and the Levant, and are of increasing importance in aquaculture (see tilapia in aquaculture). Tilapia often become problematic invasive species in new habitats, whether deliberately or accidentally introduced. (See tilapia as exotic species).
