How about a special aquarium for your dad's tropical fish? You could get him a unique, custom-designed tank that reflects his personal style and interests. You could also consider applying a tropical theme to the aquarium, such as decorating it with palm trees, coral, and other underwater plants to create a realistic environment for his fish. Alternatively, you could get him a gift card to a specialty aquarium store so he can choose some new fish or decor items to add to his current aquarium set up. A book on tropical fish keeping could also be a great gift idea that your dad would enjoy.
Or you can get him a star map with the date when he welcomed you in this world.
