Myleus Schomburgki (Wild Caught) 3.5″-4.5″

The Myleus schomburgkii, commonly known as the Black-barred Myleus or Black-barred Silver Dollar, is a striking species of freshwater fish from the family Serrasalmidae, closely related to piranhas and pacus. It’s a popular choice in large freshwater aquariums due to its distinctive appearance and peaceful schooling behavior.

• Appearance:
  • Body: Disc-shaped and laterally compressed, giving them a “silver dollar” shape.
  • Coloration: They are silver in color, with a prominent black vertical bar running across the middle of their body (hence the name “black-barred”). As they mature, some individuals may also develop hints of red or orange on their fins, particularly the anal fin.
  • Size: Myleus schomburgkii can grow quite large, up to 35 cm (14 inches) in length, although they are typically smaller in aquariums, reaching around 20–25 cm (8–10 inches).
• Habitat:
  • Native regions: Found in the rivers of South America, particularly the Amazon Basin.
  • Environment: Myleus schomburgkii inhabits fast-moving rivers and floodplains. In their natural habitat, they prefer areas with plenty of vegetation and submerged roots.

• Feeding habits: They are primarily herbivores, feeding on plant matter, algae, and fruits in the wild. In captivity, they will readily accept a wide variety of foods, including vegetables (such as spinach, lettuce, and zucchini), high-quality herbivore pellets, and occasional live or frozen food like bloodworms for variety.
• Temperament: They are peaceful, schooling fish that do best when kept in groups of five or more. Although they are related to the more aggressive piranha, Myleus schomburgkii is generally non-aggressive and gets along well with other large, peaceful fish.

• Tank size: Due to their size and active schooling nature, they require a large aquarium. A tank of at least 125 gallons is recommended for a group of these fish to allow them enough room to swim and thrive.
• Water conditions: Myleus schomburgkii prefers soft, slightly acidic to neutral water, with a pH between 5.5–7.0 and a temperature range of 24–28°C (75–82°F). They thrive in well-filtered tanks with good water movement, replicating their natural riverine habitat.
• Aquascape: The tank should include plenty of open swimming space, as well as areas with plants and driftwood to mimic their natural environment. Though they are plant-eaters, adding tough or fast-growing plants like Java fern or Anubias can still work in their tank. However, delicate plants may get nibbled on.
• Diet: In captivity, a diet focused on plant-based foods is essential. Offer a variety of leafy vegetables, herbivore pellets, and algae wafers. They will also enjoy occasional treats like blanched vegetables or fruit.

• Reproduction: Breeding Myleus schomburgkii in captivity is rare and challenging due to their size and the need for specific environmental conditions. In the wild, they breed during the rainy season in flooded areas, which is difficult to replicate in a home aquarium.

• Tank mates: Myleus schomburgkii is a peaceful fish that can be kept with other large, non-aggressive species. Ideal tank mates include other large characins (like silver dollars), peaceful cichlids (such as Severums or Uaru), and large catfish like plecos. Avoid small or slow-moving fish that could be outcompeted for food or accidentally harassed.
• Behavioral notes: Since they are schooling fish, they should always be kept in groups. A solitary Myleus can become stressed and may develop health issues or aggressive behavior as a result. When housed in a group, they display natural schooling behavior and feel more secure.

• Water quality: Maintaining pristine water quality is crucial, as Myleus schomburgkii is sensitive to poor water conditions. Regular water changes and high-efficiency filtration are necessary to keep them healthy.
• Plant consumption: Be aware that, being herbivores, they will likely nibble on most live plants in the aquarium. Artificial plants or sturdy species like Anubias or Java fern can be used as alternatives.
