In addition to the "Labeobarbus" species flock, the endemic species are "Enteromius pleurogramma", "E. tanapelagius", "Garra regressus", "G. regressus" and "Afronemacheilus abyssinicus" (one of only two African stone loaches). The remaining non-endemic species are Nile tilapia (widespread in Africa, but with the endemic subspecies "tana" in the lake), "E. humilis", "G. dembecha", "G. dembeensis" and the large African sharptooth catfish.
