Steve Gruebel owns a pet store but this is one fish that is not for sale. Named for the Hall of Fame football player, Dick Buttkiss is a Black Pacu who just turned 43 years old.

Buttkiss, who gobbles up 25 goldfish every other day, already has lived twice as long as an average pacu, a breed that is related to the piranha.

Tipping the scales at more than 20 pounds and measuring 23 inches long, Buttkiss spends his days swimming back and forth in a 4-foot-long, 75-gallon tank.
