Aquarium or Akvarium (Russian: Аква́риум) is a Russian rock group formed in Leningrad (now Saint Petersburg, Russia) in 1972. The band's second lineup was disbanded in March 2013. Despite an announcement of the group's disbanding, Aquarium has played with Grebenshchikov, Rubekin, and an otherwise new lineup of musicians since spring of 2013, and played a concert in Moscow in July 2013 with this current lineup. The band also plans a concert in Kiev in December to celebrate Grebenshchikov's 60th birthday. The band had many member changes over its 40 year history, and at the end the only remaining original member was lead singer and founder Boris Grebenshchikov. Former band members have included Anatoly Gunitsky, Dyusha Romanov, Sergey Kuryokhin, Oleg Sakmarov, and Vsevolod Gakkel.
