Never name a fish.......with that said, here's the names of my critters:
Occelaris Clown: Marvin....because, for a clownfish, he's not that funny
Purple firefish: Sheldon...my wife and I like the Big Bang Theory and this fish seems kind of neurotic.
Royal Gramma: Wallowitz...again, Big Bang Theory...and because this fish's "wardrobe" clashes like that of the character he's named for.
Skunk Cleaner Shrimp: Jacques
Convict Blennies: Stumpy and Brunhilda. Stumpy because he lost his caudal fin in a fight with his abusive beast of a girlfriend, Brunhilda
Yellow Watchman Goby: Rorschach...because he's a "Watchman" (like from the comic/movie) and he just looks p'd off.
Haven't named my possum wrasse, court jester goby, peppermint shrimp or emerald crab. Not sure if I will. I'd need to see some more personality from them before I figure out what their names are.
