The Tally Hall song most commonly associated with a fish is “Fishes,” and fandom discussions also point to “The Whale” as the main fish-themed Tally Hall-related song.

Quick scoop

  • Best direct match: “Fishes.”
  • Other fish-adjacent pick: “The Whale,” from the broader Tally Hall universe.
  • If you meant a band song with a fish in the title, “Fishes” is the clearest answer.

Why this fits

One fan discussion explicitly says, “In Fishes the song's character is a fish,” which makes it the strongest match to your question. Another discussion says the only fish-themed Tally Hall thing is “The Whale,” but that’s more of a related-universe answer than the direct song title you asked for.

Simple answer

Fishes.
