Silver Dollar Fish - Metynnis argenteus
Shallow areas of their home range that are heavily vegetated
Basically circular in shape, as long as tall, with very marked lateral compression. The front on profile of the back and stomach are not uniformly convex (out ) , but rather curve in at the Dorsal and Anal fin level. Like most members of the family (Piranha included!) they have tiny scales with small mouths and enlarged lips. The Caudal fin is slightly indented, the Adipose fin is long and short and in mature males the front part of the anal fin is crescent shaped. They can reach a size of five and one half inches, with the males smaller than the females. Coloration: The entire body is basically a strong Silver/Gray, with a high iridescence, which is highlighted when the fish are in a large school. The back is slightly darker being Greenish/Gray or Greenish/Blue in color. The Anal fin has a pale tinge of Silver color in the front that fades toward the back. The Dorsal fin is clear with a series of small dark spots. In well cared for males, the Caudal fin and the Gill cover have a Reddish border. A narrow, dark vertical band runs through each eye. As with most fish there are color variations. .
6 - 7 inches (15 - 18 cm)
5 - 10 years
Herbivore primarily, but will go after most anything you put in the tank. Give them a varied diet of fish food including algae wafers, flake, freeze dried and live foods for optimum health.
In nature these fish spawn in shallow, sun drenched flooded areas of rivers. In the home aquarium they have been breed in clear aged water with a temperature between 81 and 90f. The eggs hatch in about four days and are free swimming a week later. If well fed they will grow very quickly.
