Common Name: Gold Dust Earth Eater Cichlid
Scientific Name: Geophagus sp. "Alto Sino"
Other Names: Alto Sino Geophagus
The Gold Dust Earth Eater Cichlid is a rare and stunning Geophagus species known for its golden-yellow coloration, iridescent body, and signature earth-eating behavior. It has a sleek, elongated body with shimmering metallic hues, subtle red or blue highlights, and delicate facial markings. Like other Geophagus species, it is a substrate sifter, constantly foraging through sand in search of food. Its peaceful temperament and striking appearance make it a prized addition to South American biotope aquariums.
Habitat and Distribution:
Native to the Alto Sino region of Brazil, this species inhabits slow-moving rivers and floodplains with sandy substrates, submerged driftwood, and leaf litter. The waters are typically warm, soft, and slightly acidic, with low to moderate flow. They are often found in shallow areas where they sift through the substrate for food.
Size and Lifespan:
This species can grow up to 8-10 inches (20-25 cm) in length. With proper care, it can live for 8-12 years.
Diet and Behavior:
The Gold Dust Earth Eater Cichlid is an omnivore with a strong preference for small invertebrates and organic matter found in the substrate. In captivity, they should be fed high-quality sinking pellets, frozen or live foods such as bloodworms, brine shrimp, and daphnia, and occasional plant-based foods like spirulina flakes or blanched vegetables. They are peaceful but may become territorial during breeding. Their constant sand-sifting behavior is beneficial for maintaining a clean substrate.
Breeding and Reproduction:
Like other Geophagus species, this cichlid is a delayed mouthbrooder. The female lays eggs on a flat surface or in a shallow pit, and after initial incubation, she collects the eggs or newly hatched fry in her mouth for protection. To encourage breeding, provide a large tank with a fine sand substrate, stable water conditions, and a diet rich in protein. Fry can be fed baby brine shrimp and finely crushed flakes.
Aquarium Care and Tank Requirements:
A minimum of 75 gallons is required for a small group, but a 125+ gallon tank is recommended for optimal social interactions. Their ideal tank setup includes a soft sand substrate to allow natural foraging behavior, plenty of driftwood and rocks to create territories, moderate filtration with gentle water flow, and dim to moderate lighting to replicate their natural environment.
Ideal Tank Mates:
The Gold Dust Earth Eater Cichlid is peaceful and does well with other non-aggressive South American species. Suitable tank mates include Severums, Festivums, Angelfish, Silver Dollars, Tetras, Corydoras, and other Geophagus species. Avoid overly aggressive cichlids that may outcompete them for food or harass them.
Difficulty Level:
Intermediate. They require a fine sand substrate, stable water parameters, and a diet that supports their natural feeding behavior.
Water Parameters:
-
Temperature: 76-84°F (24-29°C)
-
pH: 6.0-7.5
-
General Hardness (GH): 3-12 dGH
-
Carbonate Hardness (KH): 2-8 dKH
-
Ammonia: 0 ppm
-
Nitrite: 0 ppm
-
Nitrate: <20 ppm (regular water changes required)
Additional Information:
- Their constant sand-sifting helps prevent debris buildup in the substrate.
- They display the best coloration when kept in a group with at least 4-6 individuals.
- A fine sand substrate is essential, as gravel can damage their delicate gill structures.
The Gold Dust Earth Eater Cichlid is a peaceful and beautiful addition to South American aquariums. With proper care, they will thrive and display their full range of natural behaviors.
