The Satanoperca Geophagus is a medium-sized, peaceful cichlid native to South America, often admired for its elegant, sandy-toned body with subtle iridescent highlights and a graceful swimming style. Known as an “eartheater” cichlid, it sifts substrate to find food, making it fascinating to watch and ideal for larger community tanks with compatible tankmates.
This species is moderate in care, thriving in stable water conditions with a soft substrate and plenty of hiding spots. It is best kept in groups or pairs to reduce stress and encourage natural behavior.
Care Requirements:
-
Tank Size: 55 gallons minimum
-
Temperature: 24–28 °C
-
pH: 6.0–7.5
-
Water Hardness: Soft to moderately hard
-
Temperament: Peaceful to semi-aggressive, social
-
Diet: Omnivore — high-quality cichlid pellets, sinking wafers, frozen or live foods, and occasional vegetables
Behavior & Compatibility:
Satanoperca Geophagus are bottom-dwelling, substrate-sifting fish that are generally peaceful but may establish minor hierarchies within groups. They coexist well with:
-
Other peaceful cichlids of similar size
-
Corydoras and other non-aggressive bottom dwellers
-
Medium-sized tetras, rasboras, and barbs
Avoid very aggressive cichlids or much smaller fish that may be stressed by their size and activity.
Tank Setup:
A planted aquarium with soft sand substrate, driftwood, rocks, and caves is ideal. Soft substrate is essential for their natural sifting behavior. Moderate water flow, stable parameters, and ample open space for swimming allow them to display their graceful movements and subtle coloration.
A peaceful, substrate-sifting cichlid with elegant patterns—perfect for larger community tanks or South American cichlid setups.
