Citizen Fish are a ska-punk band that have been together since the late 1980s. Based around Bath, England, the original members were Dick Lucas (vocals/words), Jasper (bass), Trotsky (drums), and Larry (guitar). Following their first album, Free Souls in a Trapped Environment, Larry left the band and was replaced by Phil, who, along with Dick and Trotsky, had previously been a member of the seminal British punk band, the Subhumans. Jasper and Dick had previously played together in Culture Shock.

The band is known for their lyrics, which often make strong social and political statements, dealing with themes such as anti-consumerism, vegetarianism, questioning of the status quo, and the general encouragement of people to get along with one another.

It is rumored that the band Citizen Dick from the movie Singles is an homage to Citizen Fish and its lead singer.

In 2006 they toured with and recorded a split LP with punk band Leftover Crack. This was the first Fish activity in recent years, as the members have been concentrating on Subhumans activity as of late (they did do a small East Coast/Midwest U.S. tour consisting of off-the-map bars and basements in the summer of 2005, much to the delight of dedicated fans). It also appears that drummer Trotsky has officially left the band, but is still playing with the Subhumans.
