They are hardy fish which suggests they rarely face trouble in adapting to new and human-modified environments. The species primarily have a plant-based diet, their food includes any water plant or vegetable.
As a result, they are not threatened by the unavailability of food. The large populations and absence of any substantial threats indicate that the spotted silver dollar fish are nowhere near extinction.
Apart from the wild, the fish is also a very popular aquarium fish with a pronounced presence in aquarium trades. Therefore, the actual population size can never be determined since counting the number of captive breed fry is physically impossible.
Where does a spotted silver dollar live?
The spotted silver dollars are a native species of the part of the Amazon forest belonging to northern Brazil in South America. They are also found in some rivers of French Guiana.
What is a spotted silver dollar's habitat?
The spotted silver dollars are tropical fish that live in freshwater habitats in the wild. They are found in freshwater lakes, rivers, and ponds. The fish prefers to stay in dark and peat-filled water.
Water containing dense vegetation with lots of hiding spaces is ideal for the fish. They also favor rocky substrate containing rocks and pebbles.
A river containing large debris like driftwood, weeds, and large rocks is suitable habitat. A spotted silver dollar fish size ranges from medium to large, so they require a large tank. They require plenty of plants and vegetation in the tank to imitate their wild habitat.
Keeping the tank in a dark and dim-lit place helps the fish to spawn. They also use a lot of hiding spots in their natural habitat.
Therefore, including rocks and pebbles in their tank increases their compatibility in the captive environment. They spend time on the upper part of the tank. These peaceful fishes require medium-sized peaceful fish species as their tank mates.
Who does spotted silver dollar live with?
The spotted silver dollars are medium-sized fish with a peaceful nature. They are largely schooling fish that require large space for free swimming. They do not prefer living alone in the tank and should be kept in groups of at least five.
This community fish does not breed if it is not kept in a school. To keep the fishes in their best behavior they should be kept in schools. This makes them feel protected and safe in the tank.
How long does a spotted silver dollar live?
The average lifespan of the spotted silver dollars is 10 years of age. However, compatibility with tank mates and perfect living conditions might increase the lifespan of the fish by a year or more. Genetic development of the individuals also plays a great role in the long life of the animal.
How do they reproduce?
Most of the breeding behaviors of the silver dollars are concluded by observing the breeding behavior of the captive fishes. The fish breeds in soft water.
Once the adults become ready to breed, the breeding male pursues the female fish in the water. The male will continue chasing the female until the latter gives up and the male swims closer to it.
Breeding takes place after the pairs bump into each other a few times. The male releases its sperm at the same time the female releases its eggs.
Sometimes the male is seen to wrap its body around the female when they breed. The female silver dollars lay up to 2000 eggs in a single clutch.
They lay their eggs scattered on plants so they require a well-planted aquarium. The breeding aquarium should have dim lighting as the fry are very sensitive to harsh lights.
The eggs also fail to hatch if the aquarium's lighting is not proper. The fry comes out typically after 36 hours but it also depends on the water parameters and water temperature.
They start free-swimming after a while, once they are capable of free swimming, they can be added to the big tank with the rest of the tank mates. Breeding them in captivity is easy and it is not required to feed them any special diet before spawning.
What is their conservation status?
The spotted silver dollar fish is not enlisted in the Red List published by the International Union for Conservation of Nature. The population status of the fish has not been calculated but there is no proof of any substantial threats that the fish species faces.
A large range and abundantly available plant foods help their population to increase. The fishes are used in aquarium trades but are not killed for consumption.
So even if the population from the wild decreases, it will increase the captive population. They are not endangered as of yet and the population size is expected to stay stable even in the near future.
