A friend of mine is looking to get rid of his. It ate his favorite 2 foot clown knife. The tiger shovelnose is just shy of 4 feet and lives in a 1,300 gal. pond. I assuming if your looking for a fish that can exceed 5 feet in captivity that you have the space to properly house it and feed it for it's entire life. If interested let me know and I will ask him if he still want's to give it up.
