Betta Fish Names
Bettas are famously showy and territorial — their nickname is "Siamese fighting fish" — so bold, regal, or fierce-but-pretty names tend to suit them better than a plainer community-tank fish. This page starts the generator with a betta in mind.
The Color picker below is worth setting to match your betta's actual coloring (or Multicolor for a marbled one) — bettas come in a huge range of colors, and it's an easy way to get a more tailored suggestion.

How it works
How we generate names
Written fresh, every batch
Names are generated from what you pick — species, vibe, personality, your notes — not pulled from a fixed list.
No repeats
Each new batch skips every name you've already seen this visit, so “More like these” keeps finding new ones.
