Dame Judi Dench once gave her goldfish the "kiss of life".
The "Skyfall" star has recalled how she once saved her pet fish when it was young.
Speaking on Chris Evans' How To Wow podcast, she said: "My goldfish recently died. I once gave it the kiss of life. It died when it was very little and I gave it the kiss of life and it grew to be six inches long. We kept it in a nice tank."
Meanwhile, the 85-year-old actress previously admitted she "loathes" being a national treasure as she feels it sounds like "something very, very dusty, behind a glass".
Asked if she feels pressure as a national treasure, she said "No, no, no. I loathe that word ... It's something very, very dusty, behind a glass, in a corner. I don't want to be a relic ... You know, you just get on with life, don't you?
