189 Betta Fish Names: Male, Female, Cute, Funny, Colour and Tail-Type Picks

Betta fish, also known as Siamese fighting fish, are native to the rice paddies, floodplains, and slow streams of Thailand, Cambodia, Laos, and Vietnam. They are one of the few pet fish that genuinely recognise their keeper, react to being watched, and develop individual personalities ranging from bold and theatrical to shy and methodical. A betta kept alone in a well-planted tank lives a rich solo existence — which makes naming one a more personal act than naming a fish in a community tank. This collection of 189 betta fish names covers male picks, female picks, cute options, puns, names by colour, warrior and mythology names, Thai and Southeast Asian names, names by tail type, and pop culture picks.

Male Betta Fish Names

Male betta fish are the showier sex: longer-finned, more vividly coloured, and prone to the full-flare threat display that makes them one of the most visually dramatic fish in the aquarium hobby. Names with a strong, bold sound tend to suit them well.

Male bettas cannot be housed together, which means each fish occupies its own territory and forms a distinct one-on-one relationship with its keeper. A name with a clear consonant ending or a sharp vowel cuts through the background noise of daily life and feels right when said to a fish that actually swims to the front of the tank in response.

• Apollo
• Ares
• Axel
• Balthazar
• Blade
• Blaze
• Caesar
• Cosmo
• Crimson
• Dexter
• Draco
• Duke
• Finn
• Gatsby
• Hugo
• Jasper
• Leo
• Loki
• Maverick
• Nero
• Orion
• Phoenix
• Titan
• Zeus
• Ziggy

Female Betta Fish Names

Female betta fish are often underestimated in the hobby, but they carry vivid colours, strong personalities, and in sorority tanks can display a social complexity that male bettas, as solitary fish, never develop. Names with elegance and sharpness both work well.

Female bettas have shorter fins than males but are no less beautiful. A marble female betta with black, white, and orange patches might suit Mosaic or Calico. A solid deep blue female might suit Indigo or Sapphire. Taking a few days to observe the fish before committing to a name always produces a better result than naming on the day of purchase.

• Athena
• Aurora
• Calypso
• Celeste
• Cleo
• Daphne
• Electra
• Ember
• Freya
• Iris
• Jade
• Jewel
• Khaleesi
• Luna
• Nova
• Opal
• Pearl
• Ruby
• Saffron
• Siren
• Stella
• Trixie
• Vesper
• Willow
• Xena

Cute Betta Fish Names

Cute betta fish names capture the small, darting, wide-eyed quality of a fish that can squeeze between plant leaves, hover completely still while watching its keeper, and then perform an entire threat display at its own reflection in a bubble wand.

These names work well for any betta regardless of sex or colour, particularly for bettas with softer colouring like pink, lavender, or white. For similar cute small-pet naming inspiration, the fish names guide covers a wider range of food and nature-based picks for aquarium fish.

• Mochi

Funny Betta Fish Names and Puns

Betta fish pun names have their own dedicated culture within the fish-keeping hobby, because the word “betta” itself produces wordplay that no other pet name category can match, and the fish’s warrior reputation gives celebrity and character renames extra comedy weight.

A betta named Betta Call Saul displayed on a desk tank label earns a laugh from every office visitor. These names work especially well when written on the outside of the tank, where anyone walking past reads the name before they even look at the fish.

• Aqua Fett
• Betta Call Saul
• Betta Fett
• Betta Midler
• Betta Than You
• Betta White
• Bill Nye the Science Fry
• Codfather

Betta Fish Names by Colour

Betta fish come in a wider range of colours than almost any other pet fish, including solid reds, blues, greens, blacks, whites, yellows, and purples as well as multicoloured patterns like marble, koi, galaxy, and dragon scale, making colour the most reliable naming shortcut available.

The table below maps the six most common betta colour groups to names that suit each one visually and tonally, including a row for marble and koi bettas whose multicoloured patterns open up a distinct naming lane.

Warrior and Mythology Names for Betta Fish

Betta fish were historically bred for fighting in Thailand, where matches were formally regulated and fish were valued as much for their courage as their colour, making warrior mythology names not just thematically appropriate but historically grounded for this specific species.

The Siamese name for these fish was “pla kat,” meaning tearing or biting fish, a name earned through centuries of selective breeding for aggression and endurance. Names from Greek mythology, Norse mythology, and ancient warrior cultures all carry the same energy as that history.

• Achilles
• Ajax
• Ares
• Asura
• Attila
• Brynhildr
• Genghis
• Gladiator
• Hercules
• Horus
• Lancelot
• Leonidas
• Mars
• Odin
• Perseus
• Ragnar
• Samurai
• Spartacus
• Thor
• Valkyrie

Thai and Southeast Asian Betta Names

Betta fish originate from Thailand, Cambodia, Laos, and Vietnam, and names drawn from Thai language and Southeast Asian culture give these fish an identity rooted in their actual geographic and cultural origin rather than borrowed from Western pet naming traditions.

In Thailand, the betta’s ancestral homeland, goldfish keeping is also deeply embedded in culture. For additional Asian-inspired fish naming ideas, the goldfish names guide covers a dedicated Japanese and Chinese naming section worth browsing alongside this one.

• Aroon (dawn)
• Bua (lotus)
• Chan (moon)
• Dao (star)
• Fah (sky)
• Kamon (heart)
• Khun (noble)
• Mek (cloud)
• Naga (mythical serpent)
• Phet (diamond)
• Ploy (gem)
• Raka (full moon)
• Siamese
• Surin (great warrior)
• Thip (heavenly)

Betta Fish Names by Tail Type

Betta fish are selectively bred into dozens of tail types, each with such a distinctive silhouette that the tail itself points directly to a naming angle: a Halfmoon’s full 180-degree sweep suggests grace, a Crowntail’s spiky points suggest aggression, and a Plakat’s short neat tail suggests compact efficiency.

The table below covers the five most popular betta tail types kept in the hobby and the names that suit each one’s shape and energy best.

Pop Culture Betta Fish Names

Pop culture names work especially well for betta fish because the fish’s bold, territorial, and visually dramatic personality maps naturally onto characters from fantasy, mythology, superhero franchises, and gaming, making the reference feel earned rather than arbitrary.

These names suit bettas across any colour or tail type, though matching the reference to the fish’s actual appearance gives an extra layer of appropriateness: a deep blue halfmoon betta suits Gandalf or Merlin, a vivid scarlet crowntail suits Drogon or Blaze, and an iridescent multicoloured marble betta suits Prism or Galaxy.

• Drogon
• Elsa
• Frodo
• Gandalf
• Groot
• Harry
• Katniss
• Leia
• Loki
• Maleficent
• Merlin
• Naruto
• Sansa
• Thor
• Vegeta
• Wolverine
• Xena
• Yoda
• Zelda
• Zoro

How to Choose the Right Betta Fish Name

The best betta fish name is one that connects directly to the fish’s most prominent quality, whether colour, tail type, personality, or the origin of the species, and gives the keeper a genuine reason to use it every day.

Spending two to three days observing a new betta before naming it is the most reliable method. A fish that charges the front glass the moment its keeper approaches suits a bold name like Titan or Leonidas. A fish that glides serenely through its plants without acknowledging anything suits something calmer like Luna or Vesper. Colour should be the first shortcut: a solid red betta suits Ember or Scarlet, a deep blue suits Cobalt or Indigo, a black marble suits Onyx or Shadow. Tail type adds a second layer: a Crowntail with its spiky spiked rays suits Thorn or Spike, a sweeping Halfmoon suits Crescent or Veil. The name will likely be used for three to five years, the typical lifespan of a well-cared-for betta in a heated, filtered tank, so it is worth more than thirty seconds of thought.
