Redhump Eartheater (Geophagus steindachneri)

Redhump Eartheater — Geophagus steindachneri

Fiery forehead with sand-sifting precision

The Redhump Eartheater is a striking South American cichlid known for its vibrant coloration and distinctive nuchal hump. Mature males develop a pronounced red to orange forehead hump that intensifies during breeding and dominance displays. The body carries shimmering blue-green spotting over a bronze to golden base, often highlighted with subtle red accents along the face and fins.

Native to river systems in Colombia and nearby regions, Geophagus steindachneri is a true “eartheater,” constantly sifting sand through its gills in search of small invertebrates and food particles. This natural behavior adds movement and authenticity to river-style aquariums while keeping the substrate aerated.

Growing to approximately 6–8 inches, this species remains more manageable than larger Geophagus varieties while still offering bold color and personality.
