Fish Names

Fish Names

Fish names can be as creative and silly as your heart desires — after all, fish don't know their own names! This list offers good fish names for any piscine pet that enters your aquarium.

Popular betta fish names include choices such as Blue, Moby, Bubba, and Finley. Along with Bubba, other funny fish names include Banana, Leviathan, Sheldon, and Tsunami.

Fish names are often inspired by the water, as with choices like Cove and Reef. Others relate to fish features, such as Finnegan (fins) and Gilligan (gills).

Your fish could even boast the name of a different fish, like Tuna, Trout, or Pollock. Or borrow a name of a famous fish, such as Dorothy or Klaus.

Our whole set of names for fish is listed below. You may also be interested in our page on Pet Names.

  15. RiverHeart
    • Origin:

      Nature name
