Spotted Silver Dollar 5cm

Spotted Silver Dollar 

The spotted silver dollar would have to be one of the best schooling fish for medium to large-sized aquariums, they stay at a much more manageable manageable size compared to the common silver dollar. What tends to be a surprise is that these fish are actually tetras and a very close, near-vegetarian cousin to the piranha. Even when mature, the spotted silver dollar is arguably the closest-looking fish to the red belly piranha as well. They are amazing fish to add to a larger cichlid aquarium or even a South American biotope. 

Spotted silver dollars as their name suggests have dark grey spots that run from head to tail. Spotted silver dollars have a round, dollar-like body shape and these fish also do reach around 15 cm when fully grown. This round body is covered in metallic skin that has shades of silver, blue, yellow, and jade green which all reflect light amazingly. Spotted silver dollars also have patches of tiny scales that look like stars that just shimmer under led lighting. As these silver dollars mature, they will also develop a piranha-like red belly which is especially vibrant when these fish get into breeding behaviour. Aside from their colours, silver dollars also have comically large eyes for their face and their mouth is quite small with a limited opening range but when you have a very close look at their teeth, it looks surprisingly human-like. 

Breeding spotted silver dollars is possibly in captivity however it is not incredibly common in the home aquarium. These fish need a large spawning tank and there isn’t much of a re-sale incentive considering the price these fish are in a retail setting. They breed just like any other tetra and tend to scatter eggs in dense plant material or a spawning mop. The male will fertilize the eggs however the parents do not show any protection for the fry. 

Tank Recommendations for your Spotted Silver Dollar

As the spotted silver dollar has a large footprint and prefers to be kept in schools of at least 5 fish or more, it is best to keep in an aquarium with a minimum volume of 300 litres. This ensures that they have ample swimming space since these are active fish. Spotted silver dollars can be skittish fish at times so it is always best to keep them in a system with minimal obstructions. The actual aquascape of the tank is not of major concern but a soft, sandy substrate with river stones and short pieces of driftwood will do fine for them. These fish are also massive herbivores and will essentially eat any plant they are kept with. Silver dollars are also tropical fish that are best kept at 24-26 degrees.

Suitable Tank Buddies

The spotted silver dollar is a fairly peaceful species, due to their herbivorous nature, they can generally be kept with fish of all sizes however it is best to avoid fish smaller than their mouth. 

Usually Compatible

Oscar, congo tetras, corydoras, plecos, angelfish, clown loaches, and a range of other peaceful to even semi-aggressive species. 

Sometimes Compatible

Keeping spotted silver dollars with any extremely territorial cichlids may post long-term issues with species such as jaguar cichlids constantly attacking the spotted silver dollars. 

Rarely Compatible

Any nano fish like neon tetras, endlers guppies, shrimp, and large predator fish such as barramundi or dovii which could make a meal of the smaller spotted silver dollar

Feeding your Spotted Silver Dollar

The spotted silver dollar is a fish that will take to a wide range of foods however their diet should be treated much like a lake Malawi African cichlid. These fish are omnivorous however they will really prefer to feed on plant material-based foods. Feeding them a herbivorous pellet supplemented with some frozen foods and even fruit like bananas is a great diet for them.
