A trio of fish -- brothers Milo and Oscar, along with dramatic goldfish Bea -- attend school in an aquarium in a pet store. They cope with the usual trials of teens, like dating, friendship, sports and school issues, along with some more unusual things, like giant lobster attacks and field trips to hamster cages.
