Boy Fish Names
Most fish don't show any outward sign of sex you'd notice in a home tank, so "boy fish name" is really just a naming lean rather than a biological match. This page starts the generator with that lean in mind — bold, punchy names tend to fill the slot.
Plenty of owners ignore the split entirely and just pick whatever sounds best; the vibe options in the generator below are still fully interactive if you want to try a different angle.

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.
