A tank of at least 30 gallons will be the ideal environment for this characin. Silver Dollars are a lively schooling fish and best kept in groups of three or more. Rocks, plants, and driftwood help mirror its natural habitat and will help to reduce stress on the fish, though plastic plants may be necessary due to their herbivorous nature. They do best in soft, slightly acidic water with high filtration.

The Silver Dollar will breed occasionally in an aquarium setting and a hospital or "breeding tank" with clumps of floating plants to spawn between will be necessary. Slightly acidic water is best for optimal breeding habits. After the eggs are laid removing the parents will be necessary to reduce the number of lost fry.

Silver Dollars are herbivorous and thus need plenty of vegetable matter in their daily diet. Algae tablets, flake foods or any other suitable foods should be fed multiple times daily, keeping a close watch to make sure they are getting their share from more aggressive eaters such as barbs and tetras.
