Geophagus are among the most graceful and peaceful South American cichlids, admired for their natural sand-sifting behavior, flowing fins, and subtle yet striking coloration. Often called “Earth Eaters”, these fish bring constant movement and natural beauty to large community and biotope aquariums.
Appearance & Temperament
- Coloration: Silver, gold, red, blue hues with iridescent spots
- Fins: Long flowing dorsal and caudal fins
- Adult Size: 6–10 inches (species-dependent)
- Temperament: Peaceful to semi-peaceful

Geophagus are best kept in groups, where they display natural schooling and social behavior.
Ideal Aquarium Setup for Geophagus
To maintain healthy and stress-free Geophagus, a spacious and natural setup is essential:
- Tank Size: Minimum 4 feet tank (larger preferred)
- Water Type: Freshwater
- Temperature: 24–30°C
- pH Level: 6.0–7.5
- Substrate: Fine sand (very important)

Fine sand allows safe sifting without damaging their gills.

- Vegetable-based foods for balance
Feed small portions multiple times a day to match their natural feeding style.
