Aquarium (Russian title Аквариум) is a partly-autobiographical description by Viktor Suvorov of the GRU (Soviet military intelligence directorate).

The account starts in 1969, when Suvorov, as an ordinary tank company commander, is recruited into intelligence analysis by an up-and-coming lieutenant colonel.

The reasons given are to hide his identity while the Soviet Union still existed and to protect from retaliation against friends and relatives.

The film, entitled The Aquarium (Akwarium), was directed by Antoni Krauze and stars Jurij Smolskij as Suvorov (with his Polish voice track dubbed by Zbigniew Suszyński), with Janusz Gajos, Witold Pyrkosz and Henryk Bista.

The film was a condensed version of the television series, which consisted of four episodes, and was titled: Akwarium, czyli samotność szpiega (Aquarium, or: The Loneliness of the Spy.)
