Overview
The species whose name half the eartheaters in the trade have worn at some point, and genuinely less common in tanks than the label suggests. Care is standard for the group: a shoal of five or six, a deep bed of fine sand, a long open floor, and calm mid-sized tankmates. Feed sinking granules and frozen foods in small frequent amounts. Sharp substrate is the one thing that will not work.
In the wild
Geophagus surinamensis is a Suriname endemic, restricted to the Suriname and Marowijne systems rather than spread across the continent as its trade use implies. Keep it at 25 to 29 degrees Celsius and pH 5.5 to 7.2, over several centimeters of fine sand.
Good to know
Geophagus surinamensis reaches about 21 centimeters. For decades the name was stamped on almost any striped eartheater arriving from South America, and much of the older aquarium literature under this name describes other species entirely. It is a delayed mouthbrooder.
Did you know
Most fish ever sold as surinamensis were something else; the actual species barely left its home rivers.
