Yes I agree with DW, I do have a Screen Saver which are Marine Fish swimming around.

Johnny Castaway is a screensaver released in 1992 by Sierra On-Line/Dynamix, and marketed under the Screen Antics brand as "the world's first story-telling screen saver".

The screensaver depicts a man, Johnny Castaway, stranded on a very small island with a single palm tree. It follows a story which is slowly revealed through time. It takes many days to catch on to the story. While Johnny fishes, builds sand castles, and jogs on a regular basis, other events are seen less frequently, such as a mermaid or Lilliputian pirates coming to the island, or a seagull swooping down to steal his shorts while he is bathing. Much like the castaways of Gilligan's Island, Johnny repeatedly comes close to being rescued, but ultimately remains on the island as a result of various unfortunate accidents.

The Johnny Castaway screensaver was distributed on a 3½-inch floppy disk and required a computer with a 386SX processor and Windows 3.1 as its operating system.
