Overview
The Panama eartheater is a peaceful, sociable cichlid that works the bottom of the tank. Keeping it well takes a little experience.
Did you know
The Panama eartheater is a geographic outlier. Nearly every Geophagus eartheater lives in South America. This one crossed into Central America and is the only one of its genus to make Panama home.
Caring for the Panama eartheater
Plan on at least 172 gal (650 L) with an open sand floor, since the Panama eartheater grows large and needs room. It takes mouthfuls of sand and sifts them through its gills for food. A deep, soft sand bed is essential, so avoid sharp gravel. Add some smooth wood as well.
Keep the water warm and close to neutral, at 77 to 84°F (25 to 29°C) and a pH of 6.5 to 7.8. It prefers clean, well-oxygenated conditions, so run strong filtration for a moderate current. Keep nitrate low with regular water changes.
Feed sinking pellets, granules and frozen foods such as bloodworm and brine shrimp, and make sure enough reaches the floor. It does best in a group, either one male with several females or a small mixed shoal. Lone fish can be shy, and a single pair leaves the female open to harassment. It is calm with other mild tank mates.
Males grow larger than females and carry thick lips and a fleshy forehead. It is a maternal mouthbrooder. After the pair spawns, the female takes the eggs into her mouth and holds the young there for safety. Breeding it is of medium difficulty.
Good to know
Geophagus crassilabris is a cichlid of the family Cichlidae. Most aquarium fish settle a good deal smaller than the largest recorded size.
In the wild
The Panama eartheater comes from clear streams and rivers on both slopes of central and eastern Panama. It lives over open beds of sand and fine gravel, with scattered driftwood and tree roots.
