The naming process is usually what determine which fish I'll take home. I'll look over the shelf, be pulled to a specific betta, look at them straight on and I know their name. My years as a fictional writer (hobby only) finally pay off xD.
Not to go OT. But I was majoring in English because I wanted to become a writer. Still write but changed it to psychology. I usually name them off the wall names as you see in my sig.
I've had three. First was a turquoise one named...wait for it- Turk. Then my second one was more of a royal blue, and I called him... Azul (Spanish for blue). Our current one, he is red cambodian, and I initially considered carrying on the color-inspired theme with Carmine, Adama, or Rojo, but I noticed his coloring really reminded me of a sci-fi show character I love, so Ka D'Argo he is!
Well, his name is actually Shane, because it just seemed to fit, but I later realized he was a little spider, haha. (Cashier dropped him on the floor when she was putting him in a bag!) Spider is more of a nickname. Plus he has a poster of Spider-man above his tank.
