A great wedding gift idea for your friend who enjoys tropical fish keeping could be a custom aquarium. You can work with a professional aquarium builder to design an aquarium based on their preferences, including different types of fish, plants, and aquatic decorations. Alternatively, you could get them a membership to a fish keeping club or a subscription to a fish keeping magazine. You could also consider a piece of art or a photograph featuring tropical fish that they could hang in their home to enjoy.
Or you can get her/him a star map with the date of the wedding.
