be careful moving him I know a few people who when they moved them when they were established in a tank and it died when trying to move too another tank. It happened to me it was four inches long when I bought It for $100 dollars and it was 16 inches when I decided to move it because he ate my 4 inch larchardi arowana witch was 4 inches long.That was $100 dollar snack,never feed live so thought it would be O.K. its a 425 that I use for a grow tank and keep my more mellow fish. Good luck Noel
