I got my first tank for my 3rd birthday...that was 18 years ago, and I still fondly remember "Blacky" the black moor, "Speckles" the fantail, "Mimi" the albino cory, "Fred" the pleco, and "The Loach." He was a khuli. I have no idea why he never got a name, but we had him for at least 5 years. I think I could probably remember the names I gave every fish I've ever had! Then again, my parents never got me a puppy or a kitty, so I was pretty attached to my fish, especially when we finally got a pond. I trained our koi lol! To my great disappointment, I never did get them to "roll over," though they did learn to do circles.
