Let's see... I never named all my fish... Just ones that seemed to need it. I had 2 CAEs that grew to about 5" each that I called Tweedledee and Tweedledum (dee and dum for short)... RIP and curses on the Oscar that 'et 'em. (too big for my tank, bro knew someone who'd take them, but neglected to mention the Oscar until after they were gone).
My Maroon Clown was named... Guess... Yup... Nemo... By my niece's daughter who loved that movie, and screamed "Nemo!!!" when she saw him in my tank. I had 2 Corys named Cory and Dory, and the only other critter I named was my Coral Banded Shrimp (Coral of course).
DepotFish: Hissing Cockroaches??? Where's my Raid... I'm cringing at the keyboard just typing the name. Eeeeshhh! Most people get freaked out by spiders or snakes, but with me it's roaches... Give me a nice fuzzy Tarantula or a Ball Python instead. LOL
