Amphilophus

The genus *Amphilophus* was established in 1859 by Agassiz. The genus name *Amphilophus* is a compound of *Amphi* = on both sides and *lophus* = thickening, referring to the thick lips of the type species *Amphilophus labiatus*.

Agassiz’s initial description was not very extensive and did not provide indications of characteristics for this genus. In 1906, Regan described these characteristics. They have a prominent snout; the upper jaw does not extend beyond the edge of the eye. They have long pectoral fins, and 5 to 9 vertical bands are visible on the flank.

Origin

All *Amphilophus* species originate from Central America. Three species occur on the Pacific side. On the Atlantic side, only *Amphilophus citrinellus* is found. The remaining species inhabit the crater lakes in Nicaragua.
