Fishcam refers to a television program consisting of a video camera pointed at a fishtank.
Channel 31 Melbourne, Australia, has one of the more famous and long-lasting Fishcams. There was a fishtank with a few fish in a Channel 31 control room at RMIT that was formerly used by the presentation unit. A video camera was fixed on this tank 24 hours a day. Originally C31's presentation operator would switch to Fishcam when no other programming was scheduled (where some stations would switch to a test pattern or some other meaningless broadcast). When it was discovered that Fishcam was reasonably popular, Fishcam became a scheduled show, listed in the TV guide.
