The Geophagus winemilleri, also known as the Winemiller's eartheater, is a beautiful and relatively peaceful South American cichlid. Known for its sand-sifting behavior and iridescent colors, it is a rewarding species for aquarists who can meet its specific needs. 

Tank setup
  • Tank size: A minimum of 75 gallons is required for a small group of 3 to 6 individuals. A larger tank of 125 gallons or more is ideal for a group of adults, as they can grow up to 8–10 inches long.
  • Substrate: A soft, fine sand substrate is crucial for this species. Geophagus are named "eartheaters" because they sift through sand to find food. Coarse or rough gravel can damage their gills and inhibit their natural feeding behavior.
  • Filtration: A robust filtration system, such as a high-end canister filter or sump, is necessary to handle the bioload and keep the water clean. Water flow should be present but not overly powerful, as these fish are used to slow-moving tributaries in the wild.
  • Decorations: Provide plenty of hiding spots and visual barriers using driftwood, smooth rocks, and large leafy plants. Floating plants can help to diffuse bright lighting, which they prefer.
  • Lighting: Moderate, subdued lighting is best to mimic their natural habitat. 

Water parameters
  • Temperature: Maintain a stable tropical temperature of 75–84°F (24–29°C).
  • pH: A slightly acidic to neutral pH range of 6.0 to 7.5 is ideal. While they can adapt to other conditions, stability is more important.
  • Water changes: Regular, weekly water changes of 25–30% are vital to keep nitrate levels low and maintain pristine water quality. These cichlids are sensitive to poor water conditions. 

Diet and feeding
  • Feeding method: Geophagus winemilleri are bottom-dwelling omnivores who sift through the substrate for food. They will also eat food that sinks to the bottom.
  • Food types: A varied diet is essential for their health and coloration.
    • Staple: High-quality, sinking pellets or granules with a vegetable or spirulina component.
    • Supplements: Include frozen foods such as bloodworms, mysis shrimp, and brine shrimp.
    • Vegetables: Occasional blanched vegetables, like zucchini or peas, can be offered.
  • Feeding schedule: Feed small portions multiple times a day to encourage their natural foraging behavior. 

Temperament and tank mates
  • Peaceful but territorial: This species is generally peaceful but can become more territorial and aggressive when breeding.
  • Schooling behavior: They are social and do best when kept in groups of at least 5 to 7 individuals. Keeping them in smaller numbers can lead to bullying and stress.
  • Compatible companions: Choose other large, peaceful South American fish, such as:
    • Silver dollars
    • Larger tetras
    • Uaru cichlids
    • Angelfish
    • Catfish, such as corydoras or plecos
  • Incompatible companions: Avoid any fish small enough to be considered food, overly aggressive species, and any small or delicate invertebrates. 

Breeding
  • Mouthbrooders: G. winemilleri are mouthbrooders, meaning the female carries the fertilized eggs and fry in her mouth for protection.
  • Creating pairs: To encourage breeding, keep a group of 5 or more individuals and allow them to naturally pair off.
  • Parental care: After spawning on a hard, flat surface, the female will collect the eggs in her mouth. Both parents may take turns with brooding duties, and they will guard the fry for several weeks after they become free-swimming.
