There are a lot of common names to describe and sell tropical fish. Some work, and some do not. Does a tire track eel’s body really resemble tire tracks? What is so angelic-looking about an angelfish? However, in the case of Metynnis hypsauchen, the moniker of “silver dollar” is not so erroneous a descriptor.
There are other species of fish in the Metynnis family with similar comportment and coloration, and many are commonly referred to as “silver dollars,” as well. In this article, we will be discussing the most commonly seen, the true silver dollar: Metynnis hypsauchen. Let it be known, however, that its cousins have similar requirements, and with a little extra research, they can also be kept as aquarium fish.
The silver dollar is a common fish in the aquarium hobby and has been since I started keeping fish more than 37 years ago. It has maintained its popularity through the years due to its sharp looks, ease of keeping, disposition, hardiness and relative low cost. Granted, it does not possess the garish coloring often associated with some livebearers, tetras and discus, but its shape, silvery body sheen and distinctive red anal fin capture the eye.
