The Silver Dollar fish is a popular freshwater aquarium species loved for its unique appearance and peaceful nature. Belonging to the Characidae family, which also includes tetras and piranhas, these fish are named for their round, disc-like bodies that resemble a shiny silver coin. Their reflective scales and graceful movements make them a striking addition to community tanks.

Silver Dollar fish are native to rivers and streams of South America, particularly the Amazon Basin. In the wild, they inhabit slow-moving waters with plenty of vegetation. They thrive in similar conditions in captivity, making them a great choice for aquarists who enjoy planted aquariums.

These fish are generally peaceful and do well in community tanks with other non-aggressive species. However, they are herbivorous and have a strong appetite for plants. Aquarists often provide them with leafy greens, vegetables like zucchini or spinach, and plant-based fish foods to keep them satisfied. Artificial plants or sturdy species like Java Fern are good choices for aquariums since delicate plants may be eaten quickly.

Silver Dollars are schooling fish and should be kept in groups of at least five or more. In a proper school, they feel safer, display natural behaviors, and add dynamic movement to the aquarium. They can grow fairly large, often reaching 6 inches in length, so they require a spacious tank—ideally 75 gallons or more.

When it comes to water conditions, Silver Dollar fish prefer slightly acidic to neutral water (pH 6.0–7.5) and temperatures between 72–82°F. They are hardy and adaptable, making them a good option for intermediate fish keepers.

In the right setup, Silver Dollar fish can live up to 10 years, bringing beauty and activity to an aquarium for a long time. With their shimmering scales, peaceful temperament, and schooling behavior, they are a classic favorite in the aquarium hobby.
