Common Name: Black Barred Silver Dollar
Scientific Name: Myloplus schomburgkii
Other Names: Schomburgkii Silver Dollar, Black Band Silver Dollar
The Black Barred Silver Dollar is a visually striking freshwater fish known for its distinctive black vertical bars against a shimmering silver body. This species is a member of the Characidae family and is appreciated for its peaceful nature and schooling behavior, making it an excellent addition to larger community aquariums.
Habitat and Distribution: The Black Barred Silver Dollar is native to the Amazon Basin in South America, particularly in countries such as Brazil, Peru, and Colombia. These fish inhabit slow-moving rivers, floodplains, and areas with dense vegetation and submerged roots, providing ample cover and foraging opportunities. The water in their natural habitat is typically warm, soft to moderately hard, and slightly acidic to neutral.
Size and Lifespan: In the wild, Black Barred Silver Dollars can grow up to 6-8 inches (15-20 cm) in length. In captivity, they typically reach around 6 inches (15 cm). Their lifespan can range from 10 to 15 years, depending on the care and conditions provided in the aquarium. Ensuring a proper diet, clean water, and adequate space are crucial for their longevity and well-being.
Diet and Behavior: Black Barred Silver Dollars are primarily herbivorous, feeding on plant material, algae, and fruits in the wild. In an aquarium, their diet should include a variety of plant-based foods such as blanched spinach, lettuce, and high-quality algae wafers. They can also be fed vegetable-based pellets and occasional protein sources like brine shrimp or bloodworms. These fish are peaceful and social, best kept in groups of six or more to prevent stress and encourage natural schooling behavior. They are active swimmers and prefer a well-planted tank with plenty of space to move around.
Breeding and Reproduction: Breeding Black Barred Silver Dollars in captivity can be challenging due to their specific environmental needs. They are egg scatterers, and successful breeding typically requires a large, well-planted tank with soft, slightly acidic water and a temperature slightly higher than normal. The female scatters her eggs among plants or substrate, and the male fertilizes them. There is no parental care for the eggs or fry, so a separate breeding tank or protective measures are necessary to prevent the eggs from being eaten by other fish.
Aquarium Care and Tank Requirements: To keep Black Barred Silver Dollars, a large aquarium of at least 75 gallons is recommended to provide ample swimming space and accommodate their schooling nature. The tank should include plenty of plants, driftwood, and hiding spots to mimic their natural habitat and reduce stress. A sandy or fine gravel substrate is ideal, along with moderate water flow to simulate river conditions. Efficient filtration and regular water changes are essential to maintain water quality.
Ideal Tank Mates: Black Barred Silver Dollars can be kept with other peaceful, similarly sized fish that share similar water parameter requirements. Suitable tank mates include other large tetras, peaceful cichlids, and bottom-dwelling catfish. It is important to avoid housing them with overly aggressive or significantly larger fish, as this can lead to stress or bullying.
Difficulty Level: Intermediate. While they are hardy, their specific dietary needs and preference for schooling require attentive care and a well-maintained aquarium.
