Silver Dollar Striped (Metynnis Fasciatus)
Striped Silver Dollar (Metynnis fasciatus)
The Striped Silver Dollar is a peaceful, schooling herbivore native to the Amazon River basin, specifically the Rio Madeira and Rio Tapajós. It has the classic, thin, coin-shaped body of the Metynnis genus but is distinguished by several vertical dark bars (fasciations) that run down its sides. These bars are most prominent in juveniles and sub-adults, providing excellent camouflage in the sun-dappled waters of flooded forests.
Key Information
-
Common Name: Striped Silver Dollar, Tiger Silver Dollar
-
Scientific Name: Metynnis fasciatus
-
Origin: South America (Amazon Basin, Brazil)
-
Max Size: 14–15 cm
-
Lifespan: 10+ years
-
Temperament: Peaceful but very active
-
Diet: Primarily Herbivore – They have a high metabolism for greens. Feed them spirulina pellets, blanched zucchini, peas, and high-quality vegetable flakes.
-
Care Level: Easy to Moderate
Water Parameters
| Parameter | Value |
| Temperature: | 24–28°C |
| pH: | 6.0–7.2 |
| Hardness: | 4–15 dGH |
| Minimum Tank Size: | 285L+ (75 Gallons) for a group |
Behaviour & Tank Compatibility
Like all Silver Dollars, the Striped variety is a social schooler and must be kept in groups of 5 or more. They are incredibly fast and can be quite skittish if kept in small numbers or in a tank with too much foot traffic.
They are ideal for "Community Giants" setups. They pair perfectly with Neon Blue Acaras, Severums, Geophagus, and large Loricariid catfish (Plecos).
Web Developer’s Note: If you're documenting this for a client's site, emphasize that they are "Plant Destroyers." They will eat almost anything green except the toughest plastic or silk plants.
Ideal Tank Setup
-
Break the Sightlines: Use large pieces of driftwood and river rocks to create a natural environment. This helps the fish feel secure and reduces their "flighty" behavior.
-
Open Mid-Water: They need a large "runway" for swimming. Avoid cluttering the center of the tank.
-
Lighting: They prefer moderate to low lighting. In very bright "High Tech" tanks, they may hide or appear washed out.
-
Secure Lid: Crucial. These fish are built for speed and can jump significantly high if startled by a sudden shadow or light.
-
Strong Filtration: Large schooling fish create significant waste. Ensure your filtration can handle a high bioload to keep the water crystal clear and low in nitrates.
