How about creating a personalized aquarium for your wife? You could get a custom tank and fill it with her favorite aquatic plants, rocks and decorations. You could even add some exotic fish that would complement the aquascape. This would not only be a beautiful addition to your home, but also a project that you can work on together. In addition, since it's your anniversary, you could add a special message engraved onto a plaque on the tank. This would definitely be a unique and meaningful anniversary gift that your wife will love.
