Silver Dollar (Metynnis argenteus)

The Silver Dollar or Metynnis argenteus is a freshwater fish that is named for its round shape and silver coloration. Originating in South America, this fish is often kept in an aquarium and is considered to be very easy to care for. They are also inexpensive and can be kept in groups of three or more so they work well in community aquariums.  They rarely reach more than 6" in length and can live up to 10 years old.  The males of this species will normally have a bit of red on their anal fins.  You can check out the Silver Dollar fish with your own eyes in the video below...  

If you are thinking of buying a Silver Dollar fish you will need a fish tank of about 35 gallons or so with the following water conditions, 72-77° F, KH 4-8 and pH 5.0-7.0. Providing the Silver Dollars with plants, driftwood and other hiding spots will keep this fish happy and healthy.

Silver Dollar fish are herbivores that can be fed flake food, algae tablets, and other forms of veggies. On occasion these fish will spawn in an aquarium setting. Making the water slightly acidic will help encourage breeding. If you have any additional information about the Silver Dollar please leave us a comment.
