Got him in my first year of college by winning a campus freshmen carnival game. He stayed in my dorms for those years, outliving Hedwig, the goldfish I got with him, and several others I tried to put in his tank since. He also outlived several gangs of snails, a gathering of ghost shrimp, a countless population (literally about 1000 born and died during the many years) of guppies that I bought in high school (the guppies finally died out about two years ago).
Ludwig was a good fish, no question. He loved swimming into upturned coffee mugs, making poop strings, and eating rocks to regurgitate them later. He will be buried today in the backyard in a shoebox at the time of whenever I get to it. All memorials can be made to Flakes for Fortuneless Fingerlings. Stray cats be warned: He will be sprinkled with hot sauce.
