Buttkiss, the 41 Year Old Pacu
Gothamist reports that the pacu was sold to a man named Kurt Emerick in 1968. At the time, the fish was only about two inches long but soon grew to be much bigger and became very aggressive. Emerick wasn't so psyched when the pacu started knocking things over in his fish tank, so he returned him to the pet shop, where Gruebel named him after linebacker Dick Butkus. (Gruebel likes to spell it Buttkiss.)
Gruebel has been working at the Cameo Pet Shop in Queens, New York for 47 years. He now owns the shop that originally belonged to his wife's father, and Buttkiss has been there pretty much since the beginning. "He's my mascot," Gruebel tells Paw Nation.
Buttkiss even does tricks. He comes to Gruebel's hand because he knows that's where the grub comes from. (Okay, so maybe it's not the most impressive trick, but the fish is elderly! Cut him a break!) When asked if Butkiss bites, Gruebel laughs, "Well, I stick my hand in there all the time to clean the cage and he just goes and lays in the corner."
Asked if Gruebel has done anything special to keep Buttkiss around so long, Gruebel says, "No, just feed him 20 goldfish every day, every other day depending." So why has Buttkiss lived so long? Gruebel shrugs, "I don't know." And the mysteries of longevity continue...
