Silver Dollar

The Silver Dollar is a large characin known for its round, coin-like silhouette and shimmering silver scales. Adults reach roughly 14 to 15 cm, so they need a spacious tank with plenty of length and width to swim comfortably. They're a calm, sociable fish that does best in small groups, settling into relaxed, predictable behavior once established. Their strong appetite for plants, however, makes them a poor match for lush planted aquascapes. This is a fish best suited to experienced keepers ready to commit to a large, long-term setup.

About Silver Dollar

Silver Dollar: a large, disc-shaped characin reaching 14-15cm as an adult. An advanced-level fish — learn its traits and keeping essentials.

7 things to know before welcoming a Silver Dollar

1Requires a Large Tank
Adults reach about 14 to 15 cm, so a large tank with generous length and width is essential. If keeping them in a group, plan for even more swimming space.
2Will Eat Almost Any Plant
These fish have a strong appetite for aquatic plants and will steadily strip a planted tank. If you want to maintain a lush aquascape, it's best to keep them separately.
3Calm, Social Temperament
Silver Dollars are generally peaceful and rarely aggressive toward tankmates. They do best kept in groups, showing calmer, more natural behavior than when housed alone.
4An Advanced-Level Fish
This species is considered suitable for advanced keepers. Make sure you understand tank sizing, water quality management, and feeding needs before bringing one home.
5Give Them Room to Swim
They are active, strong swimmers, so a layout with open swimming space and minimal obstacles helps them settle in comfortably.
6Maintain Stable Water Quality
As a large-bodied fish, they produce more waste, which can affect water quality more quickly. Use a filter with ample capacity and keep up with regular water changes.
7Plan Ahead for Growth
Even if small when you bring them home, they will eventually grow to nearly 14 to 15 cm. Choose your tank and equipment with their adult size in mind from the start.
