Description

The redstriped eartheater is a deep, laterally compressed cichlid of the family Cichlidae reaching about 30 cm. The silvery body shines with pearly spots and red-brown and blue lines over head and flank. Its name comes from its way of feeding: it takes mouthfuls of sand, sieves out insect larvae, worms, small crustaceans and plant matter with its gills, and spits the clean grains back out. The species comes from sandy rivers and creeks of the Guianas and the Amazon fringe. In reproduction the parents lay the eggs on a surface and take the young into the mouth when threatened. Because of its handsome colours it is popular in the aquarium hobby.
