年年有餘- Fish sounds like plentiful in Chinese and Chinese likes to use "double" for good things to come in pair. The inscription "Nian Nian You Yu" on the painting means affluence and wealth year after year. Double-fish may also symbolize "Yu Shui Zhi Huan" to reflect the happiness between the married couples as fish in water.

Note: This is a hand painting and subject to vary from the picture shown.
