A great gift idea for your granddaughter who enjoys tropical fish keeping could be a fish tank starter kit. This would include a small tank, a filter, plants, and some fish food. You could also consider a beautiful fish to add to her collection. Additionally, you could purchase a book on tropical fishkeeping or a subscription to a tropical fishkeeping magazine to help her learn more about her hobby. Another fun idea could be to take her to a local aquarium or set up a visit to a larger, exotic aquarium.
Or you can get her a star map with the date when she was born.
