Afraid I can't be much help. I gave up on naming my fish after losing a few in my early days in the hobby. I tended to name mine after their personality traits. I am sorely tempted to name my Foxface "Spaz" though, for obvious reasons.
My arrow crab is named Oliver. My cinnamon clowns are named toast and crunch. Pajama cardinal is named onesy. And my yellow watchman goby is name Richard. My wife named them.
Not to generalize ….. but I will anyhow …. I think naming fish is a wife/girlfriend/young children thing. My wife and son (when they were young) always liked to name the fish. To me, they're just fish. I'm generally not sentimental ….. wanted to name the dog dumb butt but I was informed by my sons that that's their private name for me and so would be confusing for the dog. Hrumph!
