|Scientific name||Metynnis argenteus|
|Common name||Silver Dollar|
|Natural Habitat||South America|
|Appearance||Generally disc-shaped and shiny silver in colour, hence their common name. The dorsal fin is transparent with dark spots, and the caudal fin edged with red; males have a bright red anal fin (see the large fish in the photograph.)|
|Maximum size||5 to 8 inches in length, slightly less in body depth|
|Aquarium Compatibility||Peaceful; despite their superficial resemblance and relationship to the Piranha, Silver Dollars will not harm your smaller fish. They prefer to be kept in small shoals of 3 to 5.|
|Diet||Vegetarian :Silver dollars will take chunks out of your soft-leaved plants if hungry, so supplement their diet with flake foods with a high vegetable content, available from any aquarists' supplier, and parboiled lettuce or peas. They will also take small live foods on occasion.|
My three Silver Dollars were bought as a trio less than six months ago and were barely an inch deep; they have grown at an amazing rate and the largest - clearly a male - has already reached 4 inches.
Silver dollars like to hang out together in amongst the vegetation for much of their time, so provide a well-planted tank.
