Overview
The silverspot eartheater is a mostly peaceful sand-sifter for a river tank with real current. It suits a keeper past the beginner stage.
Did you know
The silverspot eartheater sifts sand in a river famous for rapids. It pans for food where the current does half the digging.
Caring for the silverspot eartheater
Give a group of five or six silverspot eartheaters at least 119 gal (450 L), set up as a river tank. Lay a deep bed of fine sand for sifting, add smooth stone, and run pumps that keep real flow across the floor.
Keep the water clean, soft and warm, at 77 to 84°F (25 to 29°C) and a pH of 5.5 to 7.2. Given flow and clean water, it settles far faster than in a still tank. Feed sinking granules and frozen foods little and often.
The silverspot eartheater is mostly peaceful and safe in a community, so keep it with calm, mid-sized company. It is a delayed mouthbrooder, and breeding is of medium difficulty.
Good to know
The silverspot eartheater, Geophagus argyrostictus, is named for the rows of silver spangles along its flanks. It is also sold as the blue lip geophagus. Its preference for flowing, rocky stretches over quiet lagoons is unusual in the genus.
In the wild
The silverspot eartheater works sand pockets between the rapids of the Rio Xingu. The water there is warm, clear and soft, and it moves quickly over rock.
