How Deep Should a Fish Pond Be?
An outdoor fish pond is an attractive addition to any backyard landscape. While building your own fish pond might seem challenging, research and planning will help avoid errors. Koi fish and goldfish are the most popular fish for outdoor ponds. Koi fish are beautiful, though delicate and require extensive care. Goldfish are not as pretty as koi, but are more low-maintenance. However, both require a certain size pond in which to thrive.
