Geophagus sveni
Maximum Size:
Geophagus sveni can grow up to 10-12 inches (25-30 cm) in captivity, with males being larger and more colorful than females.
Native Habitat:
This species is native to South America, specifically found in the Rio Tocantins and Rio Araguaia river basins in Brazil. They inhabit slow-moving rivers with sandy or muddy substrates.
Growth Rate:
They have a moderate growth rate, taking about 2-3 years to reach their full adult size with proper care.
Life Span:
With good water quality and a balanced diet, they can live 8-12 years in captivity.
Diet (Carnivorous or Omnivorous?):
Geophagus sveni is omnivorous, meaning they consume both plant and animal matter. Their diet includes:
• High-quality pellets and flakes
• Live or frozen foods (bloodworms, brine shrimp, daphnia)
• Vegetables (blanched spinach, peas, zucchini)
• Algae wafers
They are substrate sifters, meaning they sift sand through their gills to find food, which is a common behavior among Geophagus species.
Breeding Season & Reproduction:
• Maternal mouthbrooders – the female carries fertilized eggs and fry in her mouth for protection until they are ready to swim freely.
• No fixed breeding season, but they breed more successfully in stable, warm water conditions (78-84°F or 25-29°C).
• Males are more colorful, especially during breeding, displaying vibrant red, blue, and green hues.
Best Tank Mates:
Geophagus sveni is generally peaceful and does well in a community setup with:
• Other peaceful South American cichlids (such as Severums, Uaru, and other Geophagus species)
• Large tetras (Congo Tetras, Buenos Aires Tetras)
• Corydoras catfish
• Plecos
Tank Requirements:
• Minimum tank size: 75 gallons (284 liters) for a pair or small group.
• Provide fine sand substrate to allow natural sifting behavior.
• Maintain stable water parameters: pH 6.0-7.5, temperature 76-84°F (24-29°C).
The Geophagus sveni is a stunning and peaceful cichlid, known for its beautiful coloration and unique sand-sifting behavior, making it a great choice for South American cichlid enthusiasts.
