Geophagus parnaibae

Special requirements

• Sand Substrate

  Crucial for benthophagous 'earth-eating' behavior. Coarse materials can damage sensitive gill filaments or cause internal blockages.

• Strict Water Quality

  Extremely susceptible to parameter swings and deteriorating water. Requires mature biology, over-filtration, and 50-70% weekly water changes.

• Social Grouping

  Highly gregarious; must be kept in groups of 5-8. Smaller numbers lead to heightened aggression and stress.
