**Silver Dollar (Metynnis hypsauchen) for Sale in Canada**

The Silver Dollar (Metynnis hypsauchen) is a popular South American freshwater fish admired for its distinctive round body, bright metallic appearance, and active schooling behaviour. Its shimmering silver scales catch the light beautifully, making a group of Silver Dollars an impressive addition to a spacious freshwater aquarium.

Related to the piranha family, Silver Dollars are primarily peaceful fish and are very different from their predatory relatives in everyday aquarium behaviour. They are active swimmers that enjoy the company of their own kind and are best kept in groups where they can display more natural schooling behaviour.

Because Silver Dollars grow much larger than many common community fish, they need a spacious aquarium with plenty of open swimming room. Their peaceful nature can make them suitable companions for other appropriately sized fish, including some larger community species and carefully selected monster fish.

Monster Aquarium Canada offers Silver Dollar (Metynnis hypsauchen) for aquarium hobbyists across Canada.

How Large Does a Silver Dollar Get?

The Silver Dollar (Metynnis hypsauchen) can grow significantly larger than many beginner aquarium fish.

Adults commonly reach approximately 5–6 inches (12–15 cm), although individual size can vary depending on genetics, diet, and long-term care.

Because of their active swimming behaviour, they need considerably more space than their body size alone may suggest.

Aquarium Size

A 75-gallon aquarium or larger is recommended for a proper group of adult Silver Dollars. Larger aquariums are strongly preferred for bigger schools or when keeping them with other large fish.

Recommended Aquarium Setup

Large, mature aquarium
Powerful biological filtration
Good mechanical filtration
Moderate water movement
Excellent oxygenation
Large open swimming areas
Secure aquarium lid
Smooth driftwood
Robust décor
Strongly rooted plants if used

Silver Dollars are known for eating or damaging many soft aquatic plants. If you want a planted aquarium, choose robust plants or be prepared for plant damage.

Feeding Your Silver Dollar Fish

Silver Dollars are omnivorous and should receive a varied diet with a strong vegetable component.

Recommended Foods

High-quality herbivore or omnivore pellets
Vegetable-based flakes
Spirulina foods
Blanched zucchini
Blanched spinach
Shelled peas
Other safe vegetables
High-quality frozen foods in moderation

Important Feeding Tip

A diet containing sufficient plant matter can help support healthy digestion and reduce the likelihood that Silver Dollars will constantly graze on aquarium plants.

Offer a varied diet rather than relying on a single food.

Schooling Behaviour

Keep Silver Dollars in Groups

Silver Dollars are social fish and generally feel more secure when kept with others of their own kind.

A group of 6 or more is recommended when aquarium space allows.

Keeping a proper group can encourage:

More natural swimming behaviour
Greater confidence
Reduced stress
A more impressive visual display

A larger aquarium is required as the group size increases.

Compatible Tank Mates

Silver Dollars are generally peaceful, but their adult size means they should be kept with fish that are appropriately sized.

Potential Tank Mates

Other Silver Dollars
Larger peaceful South American fish
Larger peaceful catfish
Some peaceful cichlids
Larger plecos
Other robust community fish

Silver Dollars are also sometimes kept in monster fish aquariums, but all companions must be selected carefully.

Avoid:

Very small fish that may be accidentally eaten
Extremely aggressive predators
Fin-nipping species
Fish that require very different water conditions

Always consider the eventual adult size of every fish.

Are Silver Dollars Good for Monster Fish Aquariums?

A Popular Dither Fish for Large Aquariums

In sufficiently large systems, Silver Dollars can sometimes be used as active schooling fish alongside carefully selected larger species.

Their fast swimming and relatively deep bodies can make them less vulnerable than smaller schooling fish. However, no tank mate is guaranteed to be safe with a predator.

As larger predatory fish grow, even adult Silver Dollars may eventually become potential prey.

Always monitor compatibility closely.

Silver Dollar and Live Plants

Silver Dollars are famous for their appetite for vegetation.

Plant Considerations

They may eat or damage:

Soft-leaved plants
Tender stem plants
Floating plants
Newly planted vegetation

More robust plants may survive better, but individual feeding behaviour varies.

Alternative Aquascaping Ideas

Consider:

Large driftwood
Smooth rocks
Artificial plants
Very robust live plants
Open swimming space

This approach can create an attractive aquarium without relying heavily on delicate vegetation.

Supporting Healthy Silver Colour

The bright metallic appearance of Silver Dollars depends on overall health, genetics, nutrition, and aquarium conditions.

Care Tips

Maintain excellent water quality
Keep them in an appropriate group
Provide plenty of swimming space
Feed a varied vegetable-rich diet
Avoid overcrowding
Maintain stable water parameters
Perform regular water changes

Healthy Silver Dollars are generally active, alert, and display a bright reflective sheen.
