Naming your beloved fish can be just as difficult (sometimes more so) as naming a child or dog. However, here we’ve compiled a thoughtful list of names – some humorous, some simply interesting, and others taken straight from myth and legend – to help you find a unique name that suits your equally unique koi, goldfish or fancy goldfish.
Fish Names Starting with A..,
Akarui – This is the Japanese word for “bright,” and is well-suited for goldfish and koi that are brightly colored, such as Lionhead goldfish or sparkly, metallic gin-rin koi varieties.
Autumn – A soft, sweet name for female fish with colors that inspire thoughts of the season’s warm bursts of color.
Ash – Suitable for grey, silver, or darkly speckled fish (or if you’re a fan of the popular Pokémon character).

Fish Names Starting with B…
Bubbles – A classic, albeit obvious, name choice suitable for almost any fish, particularly those with higher energy levels and a cheerful personality.
Buddy – A simple yet charming name that works for amiable, friendly fish.
Booboo Sousa – This one is really just a goofy, nonsensical name coined from a popular American show called Adventure Time; Booboo Sousa is both a teddy bear and a catchy little tune that plays at the end of some episodes, and is a name that could work for a kind or quirky fish.
Babushka – Babushka is a Russian or Polish term for an old woman, particularly one that is wise and caring.
Blaze – For brightly colored fish, or one that is very fast.
Fish Names Starting with C…

Comet – For slender fish (particularly comet goldfish!), or those that have blue-black coloring like that of a space comet.
Cypress – Cypresses are evergreen shrubs and trees with some varieties native to Asia. Part of what makes this name unique for your fish is that it not only refers to this native plant, but it’s also a bit of a play on part of the koi’s Latin name, Cyprinus (it’s full name being Cyprinus Carpio).
Fish Names Starting with D…

Whether your fish is simultaneously cowardly and curious/adventurous (like Flounder), or a bit sluggish with camouflage-like patterning (like the flounder species), Flounder is both a classic and unique name for a fish.
Frank – This one is purely a silly name, useable for really any male fish.
