Why do pet fish names sound like ordinary human names?

The Markov model is trained on banks of everyday given names, 558 male and 428 female, so it emits familiar forms like Cordelia and Harmon rather than aquatic coinages.

Are the male and female fish names generated the same way?

They use separate models. The male model trains on 558 source names and the female model on 428, so each sex draws from its own learned letter patterns.

Will I ever get the same pet fish name twice?

It can happen, but the model synthesizes fresh strings each pass from large banks, so most runs give new names like Sorrel or Ramer rather than exact repeats.

About male fish names

How male fish names are built

Pet fish names are synthesized by a Markov model trained per sex on two large banks: 558 male source names feeding the male model and 428 female source names feeding the female model. The model emits familiar, human-sounding pet labels like "Sorrel", "Cordelia" and "Harmon" that follow the statistical shape of everyday given names rather than fishy coinages. Lengths range from short "Ramer" to fuller "Lillian".

Naming notes

Unlike fantasy banks, the source here is ordinary first-name material, so the Markov output lands as cozy, recognizable pet names rather than invented words. The large 558 and 428 entry banks give the model rich transition data, which is why results read as plausible human names a fish owner would actually pick. Pick by vibe: soft -el and -er endings (Sorrel, Ramer, Harmon) feel casual, while longer -ia forms (Cordelia, Lillian) feel fancier. Both sexes draw from their own model, so tag accordingly.
