Black Fish Names
Dark scales or fins give a fish a sleek, almost shadowy look — think a black moor goldfish or a dark betta — and names tend to lean into that rather than away from it. This page starts the generator with the Color picker set to Black.
That's a starting lean, not a strict filter — add detail in the optional context box, like "mostly black with orange fins," for a closer fit, or clear it entirely for names that ignore color altogether.

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.
