Description
Scientific Name: Myleus sp. or Myloplus sp. “Blackberry” (Exact classification is debated, but it is closely related to Myleus schomburgkii). Common Name: Blackberry Silver Dollar, Blackberry Myleus Origin: South America (Amazon Basin)
Physical Characteristics This fish is often confused with the “Black Bar” Silver Dollar, but the Blackberry is generally considered a higher-grade or distinct variant.
-
The “Blackberry” Bar: It features a vertical black bar down the center of its body. In the Blackberry variant, this bar is typically wider and bolder than in the standard Single Band Dollar.
-
Coloration: Adults, especially males, develop a metallic purplish-blue tint over their silver scales (resembling the color of a blackberry). The anal fin is usually a bright, deep red and develops a “hook” shape in males.
-
Size: These are large, robust fish that can grow 8 to 10 inches (20–25 cm) in diameter.
-
Body: Like other dollars, they are tall, round, and flat (laterally compressed).
Behavior and Temperament
-
Schooling: They are social fish that need to be kept in groups of 5 or more. Due to their larger size and boisterous swimming style, they are more confident than the smaller common Silver Dollars.
-
Diet: They are herbivores. They will decimate live plants. Their diet should consist of high-quality vegetable flakes, algae wafers, and fresh foods like zucchini, peas, and cucumber.
-
Temperament: Generally peaceful, but because of their size and speed, they can be intimidating to very small fish. They do best with other large, peaceful tank mates like Severums, Oscars, or Arowanas.
Care and Habitat
-
Tank Size: Because they are large and active, a standard 55-gallon tank is usually too narrow. A 75-gallon to 125-gallon tank is recommended to give them turning radius.
-
Water Conditions: They prefer clean, well-oxygenated water with moderate flow.
-
Temperature: 75°F – 82°F (24°C – 28°C)
-
pH: 6.0 – 7.0 (Slightly acidic)
