In addition to goldfish and koi, many other fish from a wide range of families thrive in coldwater ponds, from small, colorful species, such as this Red Shiner (see also p.361), to prehistoric-looking sturgeon. However, the keeping of coldwater fish has raised environmental concerns, principally that imported exotic species may escape into the wild and endanger populations of native fish. As a result, there are legal restrictions on the sale and movement of some species. Dealers should be familiar with these laws, but you can check with the US Department of Agriculture (or, in Canada, the Department of Fisheries and Oceans) for up-to-date regulations.
