Rio Chacamax Bifasciatus Vieja Cichlid (4”)

Scientific Name: Vieja bifasciata (Common name: Vieja Rio Chacamax Cichlid, sometimes just “Bifasciate Cichlid”) Maximum Size & Lifespan: Adult Size: Up to 12–14 inches (30–35 cm) in captivity Lifespan: Around 10–15 years with proper care Recommended Aquarium Size: Single specimen or pair: 125-150 gallons Community setup with other large fish: 180 gallons or larger Tank should be at least 6 feet (180 cm) long to provide swimming space and reduce aggression. Water Parameters & Care: Temperature: 75–82°F (24–28°C) pH: 7.0–8.0 (slightly alkaline) Water Changes: 30–50% weekly, depending on stocking and filtration Filtration: Strong external filter or sump – Viejas are big eaters and heavy waste producers. Provide a sandy substrate with large rocks, driftwood, and caves. They may uproot plants, so hardy species or artificial plants are better. Tankmates: Viejas are territorial and aggressive, especially when breeding. Tankmates should be equally large and robust: Other species of vieja, Jaguar Cichlid, Large Silver Dollars and Tinfoil Barbs, Large Catfish and Plecos, Datnoid, Peacock Bass (with appropriate sizing) Avoid: small fish (will be eaten), peaceful species, or slow-moving fish. 🍽️ Diet: Omnivorous with a strong plant/protein balance: Staples: High-quality cichlid pellets (both spirulina-based and protein-rich) Frozen Bloodworms and chopped shrimp Avoid fatty foods (like beef heart) to prevent digestive issues. Overview: The Vieja Rio Chacamax is one of the most striking members of the Vieja group, displaying iridescent blue, red, and orange coloration with a bold body shape. It is intelligent, aggressive, and interactive, making it a true “wet pet” but best for advanced keepers due to its size, aggression, and tank requirements. Natural Environment: Range: Native to the Rio Chacamax, a tributary of the Usumacinta River in Chiapas, Mexico, flowing into Guatemala. Habitat: Slow to moderately flowing rivers Sandy/muddy bottoms with boulders and sunken logs Warm, alkaline water Seasonal changes in flow and water levels They feed on a mix of algae, plant matter, detritus, and small invertebrates in the wild. Breeding: Type: Substrate spawner, strong pair bonds Sexual dimorphism: Males larger, often with a nuchal hump Females smaller, more rounded body Spawning site: Flat rocks, slate, or broad surfaces Eggs: Up to 500–800 eggs per spawn Parental care: Both parents guard and fan the eggs Fry hatch in 2–3 days and are free-swimming in about a week Fry food: Infusoria or powdered fry food at first, then baby brine shrimp Parents are highly protective during breeding should only be kept alone!
