Everybody Loves Raymond

The Gift (2x9)

:

Ray, feeling guilty about only getting his dad a card for his 65th birthday, makes up for it by buying him a fancy and expensive aquarium just like the one he always admired in the Chinese restaurant. At first Frank adores the gift, but after one of the fish dies, he starts to hate it. Ray thinks it must be because the fish's demise reminded his dad of his own mortality - until he finds out the real reason and learns an important lesson about father-son relationships.
