Methuselah Is Oldest Aquarium Fish

Methuselah, believed to be the world's oldest aquarium fish, is at least 94 years old (as of 2026) and enjoys belly rubs. The 1.2-meter, 18.1-kilogram Australian lungfish arrived at San Francisco's Steinhart Aquarium from Australia in 1938, although her exact age remains unknown. Her caretakers believe she is female and say she also enjoys fresh, seasonal figs.
