Names for a pet piranha, a shoal of five or six, a mascot or a game character: South American rivers like Xingu and Orinoco, Portuguese and Spanish words like Dente and Feroz, red-belly color names, puns like Fang Gogh and ironic picks like Cuddles.

About piranha names

Most pet piranhas are red-bellied piranhas, silver fish flecked with glitter and washed red or orange underneath, and they are usually kept as a shoal. That gives a keeper three things to name after: the teeth and the reputation, the color, and the group. This list covers all three, from Dente, Incisor and Gnashville to Ember, Vermilion and Red Baron, with darker picks such as Onyx, Blackwater and Black Rhom for the black piranha, which hobbyists call a rhom and usually keep alone.

Piranhas come from the rivers of South America, so a large part of the list is geography: Xingu, Orinoco, Tapajós, Araguaia and Essequibo, river towns like Manaus and Iquitos, and Portuguese and Spanish words such as Feroz, Mordida, Colmillo and Caribe, the name piranhas go by in Venezuela. Amazon neighbors (Boto, Jacaré, Tucunaré) and folklore figures (Iara, Curupira) round that out.

The rest is humor. Aquarium piranhas are often skittish and spend a lot of time hiding behind the driftwood, which is why ironic names like Cuddles, Petal and Wallflower land so well. You will also find puns and titles (Fang Gogh, Count Nibbula), creature-feature allusions, mascot names, and ready-made sets for a shoal of five or six, such as Uno, Dos, Tres, Cuatro and Cinco.

How to choose piranha names

Name by color: a red-belly suits Ember, Vermilion or Cereja, and a black piranha suits Onyx, Carvão or Blackwater.
For a shoal, pick one theme and stay in it, such as five rivers (Xingu, Purus, Juruá, Madeira and Tapajós) or a ready-made set like Do, Re, Mi, Fa, Sol and La.
Shoal mates are hard to tell apart, so give individual names only to fish you can recognize by size, a nicked fin or behavior, and let the rest share a group name like The Xingu Six.
Irony ages well: a fish named Cuddles or Buttercup gets a laugh from every visitor, long after a name like Brutus stops being a joke.
For a team or school mascot, alliteration is easy to chant and to print: Pete the Piranha, Captain Chomp, Finley Fierce.

Frequently asked questions

What are good names for a red-bellied piranha?

Color names fit the species best: Red Baron, Ember, Crimson, Vermilion, Rojo and Vermelho all point at the red belly, while Glitter, Sequin and Stardust suit the silver flecks on the flanks. For something tougher, try Feroz, Havoc or Gnasher.

How do I name a whole shoal of piranhas?

Use a matching set or a group name. The list includes sets written out for five or six fish, such as Uno, Dos, Tres, Cuatro and Cinco or Ember, Cinder, Spark, Flare and Blaze, and group names such as The Red Belly Gang and The Lunch Bunch.

Are the Portuguese and Spanish names real words?

Yes. Dente and Diente mean tooth, Feroz means fierce in both languages, Mordida is a bite, Colmillo is a fang, and Vermelho and Rojo mean red. The river and town names, from Xingu to Iquitos, are real places in South America.

Why give a piranha a gentle name?

Because the joke works. Piranhas in a home aquarium are often shy and easily startled, so a name like Fluffy, Snuggles or Wouldn't Hurt a Fly plays the fearsome reputation against how the fish really behaves.
