About random fish names

Fish names have their own conventions because you never call a fish, you only talk about it. That frees owners to be sillier and punnier than they would be with a dog. Betta owners lean hard into wordplay (Betta Davis, Alpha Betta, Elizabetta), goldfish keepers love giving a two-dollar feeder fish a stately human name (Walter, Mildred, Gerald), and pun classics like Fin Diesel, Swim Shady, and Fishy McFishface remain unbeaten for comedy tanks. Sushi-menu names (Nori, Wasabi, Tempura, Sashimi) are affectionately morbid and universally understood.

Color is the other big driver. Bright bettas and goldfish get Ember, Mango, Sapphire, Doubloon, or Sunset; black mollies and dark plecos get Ink, Shadow, or Midnight; spotted and calico fish get Speckle, Domino, or Harlequin. Koi keepers often go a step further and use Japanese words, either variety names like Kohaku, Sanke, and Showa or nature words like Sakura, Sora, and Nami, which fit the tradition and sound elegant beside a pond. Famous fictional fish are shorthand for personality: Nemo the plucky one, Dory the forgetful one, Bruce the intimidating one, Cleo the pampered goldfish.

The names below cover all those styles, plus fish species, goldfish and betta varieties, rivers and lakes, and aquarium in-jokes, for a showpiece betta, a shoal of neon tetras, or a fish character in a children's book.

How to choose random fish names

  • Name to the color and pattern first: red and orange fish carry names like Ember, Mango, and Doubloon well, while blues suit Cobalt, Sapphire, and Azure, and spotted fish suit Speckle or Domino.
  • For a school of small fish, pick one theme (sushi menu, gemstones, planets, weather) and give each fish a name from it rather than trying to tell six identical tetras apart.
  • Bettas are solitary and get seen daily, so a personality-rich or punny name like Betta Davis or Fin Diesel gets more mileage than it would on a background fish.
  • Koi are long-lived and often bought as specific varieties, so consider a Japanese name that reflects the pattern (Kohaku for red-and-white, Ogon for metallic gold) or a nature word like Sakura or Umi.
  • Fish are frequently rehomed or replaced, so if you want a name that grows with the tank, choose one that describes the fish's role (Skipper for the boldest, Ghost for the shy one) rather than a specific individual.

Frequently asked questions

What are good names for a betta fish?

Betta owners love puns like Betta Davis, Alpha Betta, and Betta Midler, along with fiery color names like Ember, Rojo, Fuego, and Scarlet for red bettas and Cobalt, Sapphire, or Indigo for blue ones. Solo bettas also suit big personality names like Kraken or Sir Swims-a-Lot.

What should I name a goldfish?

Classic picks include Goldie, Bubbles, Nemo, and Finley, but the current trend is giving goldfish very human, old-fashioned names such as Walter, Gerald, Doris, or Mildred, plus gold-themed names like Doubloon, Bullion, and Nugget.

Do fish know their names?

Fish do not learn names the way dogs do, but many species, especially bettas, goldfish, and cichlids, learn to recognize their owner and respond to routines and sounds at feeding time. The name is really for you and anyone you introduce the fish to.

Are Japanese names traditional for koi?

Yes. Koi keeping developed in Japan, and the varieties themselves have Japanese names like Kohaku, Sanke, Showa, and Ogon. Many keepers name individual fish with those variety words or with nature words such as Sakura (cherry blossom), Sora (sky), or Nami (wave).
